Requests and proposals Spam blacklist Archives (current)→
The associated page is used by the MediaWiki Spam Blacklist extension, and lists regular expressions which cannot be used in URLs in any page in Wikimedia Foundation projects (as well as many external wikis). Any meta administrator can edit the spam blacklist; either manually or with SBHandler. For more information on what the spam blacklist is for, and the processes used here, please see Spam blacklist/About.
Proposed additions
Please provide evidence of spamming on several wikis and prior blacklisting on at least one. Spam that only affects a single project should go to that project's local blacklist. Exceptions include malicious domains and URL redirector/shortener services. Please follow this format. Please check back after submitting your report, there could be questions regarding your request.
Proposed removals
Please check our list of requests which repeatedly get declined. Typically, we do not remove domains from the spam blacklist in response to site-owners' requests. Instead, we de-blacklist sites when trusted, high-volume editors request the use of blacklisted links because of their value in support of our projects. Please consider whether requesting whitelisting on a specific wiki for a specific use is more appropriate - that is very often the case.
Other discussion
Troubleshooting and problems - If there is an error in the blacklist (i.e. a regex error) which is causing problems, please raise the issue here.
Discussion - Meta-discussion concerning the operation of the blacklist and related pages, and communication among the spam blacklist team.
#wikimedia-external-linksconnect - Real-time IRC chat for co-ordination of activities related to maintenance of the blacklist.

Please sign your posts with ~~~~ after your comment. This leaves a signature and timestamp so conversations are easier to follow.

Proposed additions (Bot reported)[edit]

Symbol comment vote.svg This section is for domains which have been added to multiple wikis as observed by a bot.

These are automated reports, please check the records and the link thoroughly, it may report good links! For some more info, see Spam blacklist/Help#COIBot_reports. Reports will automatically be archived by the bot when they get stale (less than 5 links reported, which have not been edited in the last 7 days, and where the last editor is COIBot).

  • If the report contains links to less than 5 wikis, then only add it when it is really spam
  • Otherwise just revert the link-additions, and close the report; closed reports will be reopened when spamming continues
  • To close a report, change the LinkStatus template to closed ({{LinkStatus|closed}})
  • Please place any notes in the discussion section below the HTML comment


The LinkWatchers report domains meeting the following criteria:

  • When a user mainly adds this link, and the link has not been used too much, and this user adds the link to more than 2 wikis
  • When a user mainly adds links on one server, and links on the server have not been used too much, and this user adds the links to more than 2 wikis
  • If ALL links are added by IPs, and the link is added to more than 1 wiki
  • If a small range of IPs have a preference for this link (but it may also have been added by other users), and the link is added to more than 1 wiki.

Proposed removals[edit]

Symbol comment vote.svg This section is for proposing that a website be unlisted; please add new entries at the bottom of the section.

Remember to provide the specific domain blacklisted, links to the articles they are used in or useful to, and arguments in favour of unlisting. Completed requests will be marked as {{removed}} or {{declined}} and archived.

This site offers good independent information about the Syrian civil war and it doesn't contain spam or anything like that. Honestly, I don't even know why it was put on the list in the first place but I would like to see it on the green so people can use it as reference in their articles about this conflict.

Seems to be collateral damage for a regex response to spam. We can probably do a lookbehind regex fix for this.  — billinghurst sDrewth 09:01, 18 December 2014 (UTC)


The site is in global spam-blacklisting, though it was quite enough to put in a local English list. As far as I read on talk Spam, the whole portal was blocked because of "megalomania" of his author. This is sad, but it doesn't reduce the importance of the information on the site. The "Ray Tracer Language Comparison" ( subpage of that portal is a very important RS for pages like Hindley-Milner, MLton, Stalin, Whole-program optimization, Standard ML, OCaml, Scheme, etc., and for C++ criticism. I'm sure, Jon Harrop won't spam Wiki in other languages, and there will be only a single link in each adequate page. So I request on moving the portal to local English wiki spam-blacklisting. (If he or someone will spam, the question may be decided locally.) -- Arachnelis (russian)—The preceding unsigned comment was added by Arachnelis (talk) 19:42, 23 January 2015

Adding its own website is what is called spam. Removal requests shouldn't come from people directly involved in spamming or, at least, they should come provided that *any* kind addition will cease. --Vituzzu (talk) 09:11, 29 March 2015 (UTC)[edit]

I use the software for my teaching. Wonder why it is blacklisted. —The preceding unsigned comment was added by (talk)

It was blacklisted after a spam campaign of, what likely are, people involved in the site, adding promotional language over and over after being warned.

Troubleshooting and problems[edit]

Symbol comment vote.svg This section is for comments related to problems with the blacklist (such as incorrect syntax or entries not being blocked), or problems saving a page because of a blacklisted link. This is not the section to request that an entry be unlisted (see Proposed removals above).

SBHandler broken[edit]

SBHandler seems to be broken - both Glaisher and I had problems that it stops after the closing of the thread on this page, but before the actual blacklisting. Do we have someone knowledgeable who can look into why this does not work? --Dirk Beetstra T C (en: U, T) 04:08, 30 April 2014 (UTC)

User:Erwin - pinging you as the developer. --Dirk Beetstra T C (en: U, T) 04:16, 30 April 2014 (UTC)

FYI when you created this section with the name "SBHandler", you prevented SBHandler from being loaded at all (see MediaWiki:Gadget-SBHandler.js "Guard against double inclusions"). Of course, changing the heading won't fix the original issue you mentioned. But at least it will load now. PiRSquared17 (talk) 15:30, 18 June 2014 (UTC)
Another issue is that there's a bogus "undefined" edit summary when editing the SBL log. The customization of the script via our monobooks looks also broken. Thanks. — M 10:57, 06 December 2014 (UTC)

error block[edit] 祝融八姓的新研究

I do not find in our global blacklist.  — billinghurst sDrewth 12:45, 7 January 2015 (UTC)
Test the link, it's matched by (without j). VT offers "clean". –Be..anyone (talk) 08:18, 15 January 2015 (UTC)
The rule is 'xlal[0-9a-z-]*\.com' .. that is going to be a very difficult one to whitelist, as I don't know what the original intent was to block (which may very well have included '', so excluding only the 'j' is not the way forward). I would suggest that you get '\bjxlalk\.com\b' added to your local whitelist. --Dirk Beetstra T C (en: U, T) 08:38, 15 January 2015 (UTC)
Closed Closed Please seek local whitelisting for the domain in question.  — billinghurst sDrewth 11:26, 16 January 2015 (UTC)

Bit of reference:

This was a rule that was removed after the 'blanket' xlal[0-9a-z-]*\.com was imposed. None of the additions are logged, but the '*' in the xlal-rule suggests that the string occured in multiple links with multiple characters after the xlal. --Dirk Beetstra T C (en: U, T) 04:31, 20 January 2015 (UTC)

Another one, multiple domain spamming using open proxies back in the days. The problem with these wide rules is that it is difficult to see what should be covered and what we can 'let through'. is defined as a malicious site by my internet filter. --Dirk Beetstra T C (en: U, T) 05:33, 20 January 2015 (UTC)

  • I reviewed the history of the blacklisting. See Talk:Spam_blacklist/About#Old_blacklisting_with_scanty_history. is not registered at this time. is registered in China, and may not be connected with the original spammer, but the site is not functional anyway, it does not respond to pings.
  • shows no sign of being connected. The original spam was in a short period over 8 years ago, and was apparently not cross-wiki. This was before had a spam blacklist, so all blacklisting was done here. This should not be on the spam blacklist. In 2008, the admin who added it attempted to remove all his listings, and that was reverted. Maybe it's time to clean this one up. If nothing else the original regex could be eliminated and the specific sites added, so that is not caught. But I simply removing it is easiest and harmless. --Abd (talk) 01:35, 21 January 2015 (UTC)
    • xlalu is defined as a malicious site by my internet filter, and I am still not sure if it is only xlale and xlalu, it may have also been xlalk and xlulabd that have been spammed. I AGF on the admin who added the rules that there was a reason for its broadness. You may be very right that the current owner of the site may have nothing to do with the spam, it may also be that the past abuser did not have anything to do with the site, but was abusing the site to make some point here on Wikipedia. It is not always a site-owner that is the spammer, and for the more sophisticated spammers, it is likely not the site-owner that spams.
    • I know that does not show any sign of being connected, what I do see is just ONE wiki where ONE link is needed, and here a regex where exluding specifically is giving a too difficult rule. And excluding specific domains from a rule is exactly why Wikis have a whitelist. --Dirk Beetstra T C (en: U, T) 05:53, 21 January 2015 (UTC)

... --Dirk Beetstra T C (en: U, T) 05:58, 21 January 2015 (UTC)

This is a can of worms, I find now also dozens of 'domains' spammed by dozens of SPAs (open proxies?) - both deleted and existing diffs on many different pages. This shows that the IPs were active globally (this edit is clearly of the same type of the spamming edits on en.wikipedia, though here no links were included). My advice stays: whitelist it locally, or show me exactly what was abused and we might consider a narrowing-down, excluding some collateral damage (as I said earlier, gives me a 'malicious site'-warning, I don't think that wholesale removal is a good idea). --Dirk Beetstra T C (en: U, T) 06:13, 21 January 2015 (UTC)

Thanks, Beetstra. would fit a reasonable pattern used by the spammers. It's a "domain for sale." Dropped twice. However, is dead, and was dropped four times (nobody owns the domain, so your browser is relying on something old, that probably was not the original spammed domain owner. After all, it's been over eight years). is not an active site, and is unlikely to be the original owner either. It was dropped four times as well.
The wikibooks link cited shows as editing Wikibooks once, no spam. Global contributions show 5 edits with no visible relation to the xlale, xlalu, and xlala spammers. No spam, except one link [5] adding ひきこもり. How is this edit "of the same type of spamming edits on en.wikipedia"? We only have seen Contributions/ The IP on enwiki added "Cool site!" followed by a series of links that could be highly deceptive, i.e., imitating real insurance company pages. Obviously, you may have seen more than that, but the Wikibooks IP added "Hi, you have very good site! Thank you!" This IP shows zero sign of being a spammer. The single link added is not blacklisted.
Yes, if there were a substantial reason to continue the blacklisting, then the whitelisting solution would make some sense. However, whitelisting is quite impractical for most users. I've researched problem blacklistings, and saw what happened with users. Very few will request a whitelisting, they just give up. And for some of those who do, the request sits for months. Many admins are clueless about the whole process, not to mention users.
Beetstra, I think you have never understood this. You see one request from one wiki. For every one request, there are likely dozens or more users frustrated who just give up. Ordinary users do not come to meta for delisting requests, especially if English is not their language. --Abd (talk) 21:11, 21 January 2015 (UTC)
The diff I gave uses the same language, same edit summary as the spammers, that editor is the cross-wiki spammer, the same person. The diff you gave on ja.wikipedia is not the spammer, it is a physically different person. --Dirk Beetstra T C (en: U, T) 03:22, 22 January 2015 (UTC)
"I've researched problem blacklistings, and saw what happened with users. Very few will request a whitelisting, they just give up." .. HOW do you know that a user gives up in stead of requesting whitelisting/deblacklisting. If you know it is a 'problem blacklisting' (as you call it), someone must have .. gone through the point of mentioning that it was a problem (e.g. ask for de-listing/whitelisting), otherwise you do not know what the intention was of the editor who ran into the blacklisting, you don't even know whether users ran into the rule. 'For every one request, there are likely dowzens or more users frustrated who just give up'. Yet, ZERO evidence that even one user ran into the rule, or, if users ran into the rule, that they were not actually spammers trying to add the link. --Dirk Beetstra T C (en: U, T) 05:22, 22 January 2015 (UTC)
We're done again, you found it necessary to make it personal again (as usual defense in these threads), ánd make yet more sweeping statements without evidence. If someone else has something substantial to add we can discuss further. --Dirk Beetstra T C (en: U, T) 03:22, 22 January 2015 (UTC)

Symbol comment vote.svg This section is for discussion of Spam blacklist issues among other users.

Expert maintenance[edit]

One (soon) archived and rejected removal suggestion was about matched by a filter intended to block One user suggested that this side-effect might be as it should be, another user suggested that regular expressions are unable to distinguish these cases, and nobody has a clue when and why was blocked. I suggest to find an expert maintainer for this list, and to remove all blocks older than 2010. The bots identifying abuse will restore still needed ancient blocks soon enough, hopefully without any oogle matching google cases. –Be..anyone (talk) 00:50, 20 January 2015 (UTC)

No, removing some of the old rules, before 2010 or even before 2007, will result in further abuse, some of the rules are intentionally wide as to stop a wide range of spamming behaviour, and as I have argued as well, I have 2 cases on my en.wikipedia list where companies have been spamming for over 7 years, have some of their domains blacklisted, and are still actively spamming related domains. Every single removal should be considered on a case-by-case basis. --Dirk Beetstra T C (en: U, T) 03:42, 20 January 2015 (UTC)
Just to give an example to this - redirect sites have been, and are, actively abused to circumvent the blacklist. Some of those were added before the arbitrary date of 2010. We are not going to remove those under the blanket of 'having been added before 2010', they will stay blacklisted. Some other domains are of similar gravity that they should never be removed. How are you, reasonably, going to filter out the rules that never should be removed. --Dirk Beetstra T C (en: U, T) 03:52, 20 January 2015 (UTC)
By the way, you say ".. intended to block .." .. how do you know? --Dirk Beetstra T C (en: U, T) 03:46, 20 January 2015 (UTC)
I know that nobody would block if what they mean is, or vice versa. It's no shame to have no clue about regular expressions, a deficit we apparently share.:tongue:Be..anyone (talk) 06:14, 20 January 2015 (UTC)
I am not sure what you are referring to - I am not native in regex, but proficient enough. The rule was added to block, at least, and (if it were ONLY these two, \bxlal(u|e)\.com\b or \bxlal[ue]\.com\b would have been sufficient, but it is impossible to find this far back what all was spammed, possibly, and were abused by these proxy-spammers. --Dirk Beetstra T C (en: U, T) 08:50, 20 January 2015 (UTC) may have been one of the cases, but one rule that was blacklisted before this blanket was imposed was '' ( rule was removed in a cleanout-session, after the blanket was added). --Dirk Beetstra T C (en: U, T) 04:45, 20 January 2015 (UTC)
The dots in administrative domains and DNS mean something, notably is typically related to an administrative bar.example domain (ignoring well-known exceptions like etc., Mozilla+SURBL have lists for this), while foobar.example has nothing to do with bar.example. –Be..anyone (talk) 06:23, 20 January 2015 (UTC)
I know, but I am not sure how this relates to this suggested cleanup. --Dirk Beetstra T C (en: U, T) 08:50, 20 January 2015 (UTC)
If your suggested clean-ups at some point don't match the request by a Chinese user would be satisfied—as noted all I found out is a VirusTotal "clean", it could be still a spam site if it ever was a spam site.
The regexp could begin with "optionally any string ending with a dot" or similar before xlalk. There are "host name" RFCs (LDH: letter digit hyphen) up to IDNAbis (i18n domains), they might contain recipes. –Be..anyone (talk) 16:56, 20 January 2015 (UTC)
What suggested cleanups? I am not suggesting any cleanup or blanket removal of old rules. --Dirk Beetstra T C (en: U, T) 03:50, 21 January 2015 (UTC)
  • I have supported delisting above, having researched the history, posted at Talk:Spam_blacklist/About#Old_blacklisting_with_scanty_history. If it desired to keep and on the blacklist (though it's useless at this point), the shotgun regex could be replaced with two listings, easy peasy. --Abd (talk) 01:42, 21 January 2015 (UTC)
    As I said earlier, are you sure that it is only xlale and xlalu, those were the two I found quickly, there may have been more, I do AGF that the admin who added the rule had reason to blanket it like this. --Dirk Beetstra T C (en: U, T) 03:50, 21 January 2015 (UTC)
Of course I'm not sure. There is no issue of bad faith. He had reason to use regex, for two sites, and possibly suspected additional minor changes would be made. But he only cited two sites. One of the pages was deleted, and has IP evidence on it, apparently, which might lead to other evidence from other pages, including cross-wiki. But the blacklistings themselves were clearly based on enwiki spam and nothing else was mentioned. This blacklist was the enwiki blacklist at that time. After enwiki got its own blacklist, the admin who blacklisted here attempted to remove all his listings. This is really old and likely obsolete stuff. --Abd (talk) 20:07, 21 January 2015 (UTC)
3 at least. And we do not have to present a full case for blacklisting (we often don't, per en:WP:BEANS and sometimes privacy concerns), we have to show sufficient abuse that needs to be stopped. And if that deleted page was mentioned, then certainly there was reason to believe that there were cross-wiki concerns.
Obsolete, how do you know? Did you go through the cross-wiki logs of what was attempted to be spammed? Do you know how often some of the people active here are still blacklisting spambots using open proxies? Please stop with these sweeping statements until you have fully searched for all evidence. 'After enwiki got its own blacklist, the admin who blacklisted here attempted to remove all his listings.' - no, that was not what happened. --Dirk Beetstra T C (en: U, T) 03:16, 22 January 2015 (UTC)
I searched all the logs (Special:Log/spamblacklist) of several wikis using the regexp entry /xlal[0-9a-z-]*\.com/.
There were almost no hits:
w:ca: 0
w:ceb: 0
w:de: 0
w:en: 1: 20131030185954,
w:es: 1: 20140917232510,
w:fr: 0
w:it: 0
w:ja: 0
w:nl: 0
w:no: 0
w:pl: 0

w:ru: 0
w:sv: 0
w:uk: 0
w:vi: 0
w:war: 0
w:zh: 1: 20150107083744,
So there was just one single hit at w:en (not even in the main namespace, but in the user namespace), one in w:es, and one in w:zh (probably a false positive). So I agree with user:Abd that removing of this entry from the sbl would be the best solution. -- seth (talk) 18:47, 21 February 2015 (UTC)
Finally an argument based on evidence (these logs should be public, not admin-only - can we have something like this in a search-engine, this may come in handy in some cases!). Consider removed. --Dirk Beetstra T C (en: U, T) 06:59, 22 February 2015 (UTC)
By the way, Seth, this is actually no hits - all three you show here are collateral. Thanks for this evidence, this information would be useful on more occasions to make an informed decision (also, vide infra). --Dirk Beetstra T C (en: U, T) 07:25, 22 February 2015 (UTC)
I am not sure that we want the Special page to be public, though I can see some value in being able to have something at ToolLabs to be available to run queries, or something available to be run through quarry.  — billinghurst sDrewth 10:57, 22 February 2015 (UTC)
Why not public? There is no reason to hide this, this is not BLP or COPYVIO sensitive information in 99.99% of the hits. The chance that this is non-public information is just as big as for certain blocks to be BLP violations (and those are visible) ... --Dirk Beetstra T C (en: U, T) 04:40, 23 February 2015 (UTC)

Now restarting the original debate[edit]

As the blacklist is long, and likely contains rules that are too wide a net and which are so old that they are utterly obsolete (or even, may be giving collateral damage on a regular basis), can we see whether we can set up some criteria (that can be 'bot tested'):

  1. Rule added > 5 years ago.
  2. All hits (determined on a significant number of wikis), over the last 2 years (for now: since the beginning of the log = ~1.5 years) are collateral damage - NO real hits.
  3. Site is not a redirect site (should not be removed, even if not abused), is not a known phishing/malware site (to protect others), or a true copyright violating site. (this is hard to bot-test, we may need s.o. to look over the list, take out the obvious ones).

We can make some mistakes on old rules if they are not abused (remove some that actually fail #3) - if they become a nuisance/problem again, we will see them again, and they can be speedily re-added .. thoughts? --Dirk Beetstra T C (en: U, T) 07:25, 22 February 2015 (UTC)

@@Hoo man: you have worked on clean up before, some of your thoughts would be welcomed.  — billinghurst sDrewth 10:53, 22 February 2015 (UTC)
Doing this kind of clean up is rather hard to automatize. What might be working better for starters could be removing rules that didn't match anything since we started logging hits. That would presumably cut down the whole blacklist considerably. After that we could re-evaluate the rest of the blacklist, maybe following the steps outlined above. - Hoo man (talk) 13:33, 22 February 2015 (UTC)
Not hitting anything is dangerous .. there are likely some somewhat obscure redirect sites on it which may not have been attempted to be abused (though, also those could be re-added). But we could do test-runs easily - just save a cleaned up copy of the blacklist elsewhere, and diff them against the current list, and see what would get removed.
Man, I want this showing up in the RC-feeds, then LiWa3 could store them in the database (and follow redirects to show what people wanted to link to ..). --Dirk Beetstra T C (en: U, T) 03:30, 23 February 2015 (UTC)
I created a table of hits of blocked link additions. Maybe it's of use for the discussion: User:lustiger_seth/sbl_log_stats (1,8 MB wiki table).
I'd appreciate, if we deleted old entries. -- seth (talk) 22:12, 26 February 2015 (UTC)
Hi, thank you for this, it gives a reasonable idea. Do you know if the rule-hits were all 'correct' (for those that do show that they were hit) or mainly/all false-positives (if they are false-positive hitting, we could based on this also decide to tighten the rule to avoid the false-positives). Rules with all-0 (can you include a 'total' score) would certainly be candidates for removal (though still determine first whether they are 'old' and/or are nono-sites before removal). I am also concerned that this is not including other wikifarms - some sites may be problematic on other wikifarms, or hitting a large number of smaller wikis (which have less control due to low admin numbers). --Dirk Beetstra T C (en: U, T) 03:36, 8 March 2015 (UTC)
We probably can't get information of false positives automatically. I added a 'sum' column.
Small wikis: If you give me a list of the relevant ones, I can create another list. -- seth (talk) 10:57, 8 March 2015 (UTC)
Thanks for the sum-column. Regarding the false-positives, it would be nice to be able to quickly see what actually got blocked by a certain rule, I agree that that then needs a manual inspection, but the actual number of rules with zero hits on the intended stuff to be blocked is likely way bigger than what we see.
How would you define the relevant small wikis - that is depending on the link that was spammed? Probably the best is to parse all ~750 wiki's, make a list of rules with 0 hits, and a separate list of rules with <10 hits (and including there the links that were blocked), and exclude everything above that. Then these resulting rules should be filtered by those which were added >5 years ago. That narrows down the list for now, and after a check for obvious no-no links, those could almost be blanket-removed (just excluding the ones with real hits, the obvious redirect sites and others - which needs a manual check). --Dirk Beetstra T C (en: U, T) 06:59, 9 March 2015 (UTC)
