Make sure you have a good reason for the check. It will only be accepted to counter vandalism or disruption to Wikimedia wikis. Valid reasons include needing a block of the underlying IP or IP range, disruptive sockpuppetry, vote-stacking, and similar disruption where the technical evidence from running a check would prevent or reduce further disruption.
Be specific in your reasons. Ambiguous or insufficient reasons will cause delays. Explain the disruption and why you believe the accounts are related, ideally using diff links or other evidence.
Make sure there are no local checkusers or policies.
Reason(s): *Bodybuilder1991 already confirmed as Sci-fi/Michaelskater, connected with the Anglo Pyramidologist (AP) sock farm, Liftingthe admits being Bodybuilder1991, and see recent checkuser for (Storyfellow et al). MrRowser was a very weak suspect previously but from recent activity was clearly AP. The next three are disruptive impersonation socks, a known AP behavior, impersonating a known AP target. The last two are suspicion based on recent editing, was fast with news of high AP interest (created by him), which may be a coincidence.
Two brothers are actually behind the sock family, recently admitted, but they live not far from each other, sometimes sharing IP address, and are often involved with each other's issues. Open proxies are sometimes used.
I have IP evidence I am sending by email to the stewards list for privacy reasons. Thanks. Abd (talk) 01:15, 1 February 2018 (UTC)
@Abd: Have you send it to stewardswikimedia.org? As emails from outsiders to stewards-l are automatically rejected. Trijnsteltalk 01:55, 2 February 2018 (UTC)
Yes. I got a response from Vito, so I know it went to the right list. (He does not seem to have understood the mail. I am not asking for checkusers to reveal any private information, nor to connect IP addresses to real persons, nor to act based on the information I provided, other than, say, police may investigate an anonymous tip. They will not arrest someone solely on such a tip. I provided a list of IP addresses that were clearly the relevant sock master from the duck test, and that might be useful in connecting the named accounts. If not, it can be disregarded.) I also provided certain normally private information, legally collected, but I do not want to describe it here. w:WP:BEANS Thanks. --Abd (talk) 02:04, 2 February 2018 (UTC)
Indeed I didn't understand it was just "an anonymous tip". In other words a request to violate a basket of policies and laws basing upon illegally collected, untrustworthy and useless data. --Vituzzu (talk) 10:10, 2 February 2018 (UTC)
It was not anonymous, but private, as such should be. ("Anonymous tip" was an analogy.) It was not a request to violate any identified policy, and no evidence was collected illegally. Vituzzu is making serious claims without evidence (and, by the way, after he made this "illegal" claim, I researched the law and found nothing), but this is irrelevant here. This is a checkuser request, and what I submitted to the checkuser mailing list will be used or not, at the discretion of the acting steward. If there are any questions about the request, I'll answer; until then I'm simply waiting. I am not biased toward positive results, a finding of clear independence would be of equally high interest to me. There are intermediate findings that would still be valuable. Please, just the facts, as possible. (One of the accounts above was added to a prior request by another user from Wikiversity, but it was not noticed and that had been archived.) --Abd (talk) 04:16, 3 February 2018 (UTC)
I don't trust your knowledge of policies, nor your "researches". That's both against law and policies, there's no much room for lawyering. Also I think you're just using this particular LTA (who is anything but smart) as an easy front for your en.wikiversity agenda. Both @Mu301: and @Ajraddatz: already outlined, these requests are not useful: most of these accounts are already checked at en.wiki or are easy catch for duck test. --Vituzzu (talk) 21:53, 3 February 2018 (UTC)
At en-wv there's a grand total of just 4 edits from Bodybuilder1991 (all of them on my talk page) and one from Liftingthe (also on my talk page.) I was not able to provide assistance in this case, but I do consider it legitimate that someone at least be allowed to make a request to a local 'crat even if they've been blocked elsewhere. I do not appreciate an indef blocked user like Abd interfering with these communications as we attempt to respond to complaints on our wiki. (and there have been many complaints from Abd's activity...) I see no edits at en-wv from any of these accounts that warrants CU, and consider this to be a frivolous and nuisance request. These vendetta's that you are pursuing are a large part of the reason why you can no longer participate at Wikiversity. @Abd: your wv user talk page is now locked. You no longer have an "agenda" to pursue at Wikiversity. Please stop wasting everyone's time. --mikeutalk 03:36, 4 February 2018 (UTC)
(Not documented in the previous request.) The point of this request is not that sock, which was indeed obvious, but the connection between the Michaelskater family, already found to be behind impersonation socks, and to be Bodybuilder1991, and new impersonation and other socks on Wikipedia, as well as previously reported IP addresses apparently involved in the same issues, cross-wiki. This can make a difference in further discussions. As to "wasting time," I have filed a substantial series of checkuser requests, all quite productive. Someone, though really doesn't want this to happen and has been complaining extensively by email to some, who seem to believe the claims. This page is for checkuser requests. not debates, and hopefully this one will be addressed or closed. Thanks. --Abd (talk) 23:53, 4 February 2018 (UTC)
w:user:El Badboy!'s last edit on Wikipedia was at 13:51, 25 January 2018, only edit by v:user:Liftingthe was at 19:31, 25 January 2018, and account registered on Wikiversity at 18:43, 25 January 2018, which is timing, and another impersonation.
At 21:45, 25 January 2018 w:Tumbleman_2018 deleted an edit by w:user:Krelnik that began with "A post at the "Wikipedia We Have A Problem" blog (I'd link it but naturally it is blacklisted) is soliciting readers to go edit two articles that have figured in past fringe-related edit wars and attempt to relitigate past battles on the talk page. The first request is to go to w:Rupert Sheldrake and ask about the word biologist in the first sentence (despite the fact that it is already right there in the second sentence). The second request is to go to w:Deepak Chopra and ask about "why he isn't listed as an MD", again despite the fact that this is right there in the second paragraph." is attempting to turn every conversation into an attack on favorite targets, a common AP sock behavior, here included w:user:Krelnik.
The above includes deception.
The above includes a request for contributors to pressure others.
At 18:08, 14 February 2018 w:Tumbleman Wins reattacked w:Deepak Chopra with "wikipediawehaveaproblem.com/2018/01/come-play-wikipedias-blp-pallooza/", which is an attack on favorite targets, a common AP sock behavior.

Hi, I've already sent emails about this ongoing harassment by Abd to stewards by email; I'll probably send another. The above spam is from abd, yet he just has this other user now post it - hence he still links to his coldfusion blog. The above spam is misinformation; most those accounts are completely unrelated. Just read this to see what is really going on - Lomax is perm-banned on Wikiversity and RationalWiki and blames "Anglo Pyramidologist" for those bans. He now has a vendetta against Anglo P, for example his blog now has 19 (!) smear articles attacking this person. Wikiversity perm-blocked him for this vendetta.Fairbournes (talk) 22:59, 20 February 2018 (UTC)
User ΕρΚιλλ created his account on 19 January 2018, 3 days after his previous confirmed puppet (Vlad Mirsic) was permanently banned from el.WP . From the day Vlad Mirsic was banned, a number of users were deemed as Vrahomarinarer's puppets and therefore banned (User: Πικουλιν, User:Μαύρος Πιτ, User:Φαμαγκούστα, User:VIM7, User: Ρακί ή ουίσκι!

Reason(s): We have strong evidence to believe that Biberi is a sock of Hatake. They offended the blocking admin and in their first two days of editing they edited 15 articles that Hatake had edited, with editing skills of an experienced user. See also this report: .
