Archives (current)→

The associated page is used by the TitleBlacklist MediaWiki extension, and lists strings of regular expressions that may not be used as page titles or usernames on any Wikimedia projects. Any Meta-Wiki administrator or steward can edit this blacklist.

For more information on what the title blacklist is for, and the processes used here, please see Title blacklist/About.

Please post comments to the appropriate section below: Proposed additions, Proposed removals, or Troubleshooting and problems, read the messageboxes at the top of each section for an explanation. Also, please check back some time after submitting, there could be questions regarding your request. In addition to that, please sign your posts with ~~~~ after your comment.

Completed requests are archived, additions and removal are logged.

Proposed additions

This section is for proposing that a page title be blacklisted; add new entries at the bottom of the section. Provide links demonstrating widespread creation by multiple users or IP's. Completed requests will be marked as done or denied and archived.

• Proposed usernames can be checked at toollabs:meta/gusersearch/
• Proposed Pagetitles can be checked at toollabs:global-search

Shit

There are a lot of inappropriate usernames (including some very recent ones) containing "shit". We can't just blacklist all of them with .*SHIT.* <newaccountonly>, because there are many legitimate names containing the string "shit" (especially Indian names), but we could probably blacklist a lot of them with something like .*\b(?:BULL)?SHIT\b.* <newaccountonly>. Unfortunately gUser search doesn't seem to support \b in regexes, but I tried searching for .*(?:^|[ -!?,])(?:BULL)?SHIT(?:[ -!?,]|$).* and checked the last 100 usernames that match, and pretty much all of them are blatantly inappropriate. The only matching username I found that might be OK is Dr. Pravat Kumar Shit, but I feel like that's probably a joke name, so we could try adding .*\b(?:BULL)?SHIT\b.* <newaccountonly>. If that is a legitimate name, or if there are other legitimate names like that, we could try adding .*\b(?:BULL)?SHIT\b(?!(?:$| )).* <newaccountonly>, which would allow usernames containing "shit" followed by a space, as well as usernames ending with "shit".

Phonetic extensions, superscripts and subscripts

Although the mathematical letterlike symbols are now blocked, I see people are still abusing unusual Unicode characters to create confusing and unsearchable novelty usernames, the latest being en:User:ᵗʰᵉ ᵇᵒᵘʳⁿᵉ ᵘˡᵗⁱᵐᵃᵗᵘᵐ !!. While this isn't a massive problem - at the moment this is the only one I've seen - I think it would still be a good idea to block this "fancy text" loophole by blocking the en:Phonetic Extensions, en:Phonetic Extensions Supplement and en:Superscripts and Subscripts Unicode blocks from use in usernames.

As far as I can see, these characters are not used in any natural language, so there shouldn't be any adverse effects from blocking these for usernames. However, I can see cases in which these characters might be appropriate in article titles, so I won't suggest blocking these for titles.

The regex for this would be:

.*[\x{1D00}-\x{1DBF}\x{2070}-\x{209F}].* <newaccountonly> # Phonetic extensions, superscripts and subscripts

Proposed removals

This section is for proposing that a title be unlisted; please add new entries at the bottom of the section. Remember to provide the specific title or regex blacklisted, links to the articles they are used in or useful to, and arguments in favour of unlisting. Completed requests will be marked as done or denied and archived. The addition or removal of a title is not a vote, please do not bold the first words in statements.

Troubleshooting and problems

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 title. This is not the section to request that an entry be unlisted (see Proposed removals above).
