Meta-Wiki is home to a number of blacklists.
These are lists of various types of entities not allowed on any Wikimedia projects:
- Spam blacklist - A list of website links that are not accepted by the software. This is most likely the page you are looking for.
- Title blacklist - A list of page titles and usernames not allowed by the software. Local administrators are unaffected by this list.
Local blacklists & whitelists
While these specific pages only affect Meta, each project has its own version of this that administrators on that project may edit to customize site behavior.
These are local-only versions of the above.
Whitelists are specific exceptions to the above blacklists.
- MediaWiki:Autoblock whitelist - IPs exempt from autoblocks when you block a username.
- MediaWiki:Captcha-addurl-whitelist - A list of website links that will not trigger the anti-spam captcha.
- MediaWiki:Bad image list - A list of specific images and the pages that they may be used on. The first pagename will be the image, subsequent pages are the page exceptions.
