The following instructions were copied from mw:Extension:Title Blacklist.

The title blacklist is maintained as a system message MediaWiki:Titleblacklist.

This page consists of regular expressions, each on a separate line. For example:

Foo <autoconfirmed|noedit|errmsg=blacklisted-testpage> 
Bar #No one should create article about it

There is no need to use "^" at the beginning and "$" at the end; these are added automatically.

Each entry may also contain optional attributes, enclosed in <> and divided by |

  • autoconfirmed — only non-autoconfirmed users are unable to create/upload/move such pages
  • noedit — users are also unable to edit this article
  • casesensitive — don't ignore case when checking title for being blacklisted
  • errmsg — the name of the message that should be displayed instead of standard

When the action is blocked, one of the following messages is displayed together with the filter row (as $1): titleblacklist-forbidden-edit, titleblacklist-forbidden-move, titleblacklist-forbidden-new-account or titleblacklist-forbidden-upload. Generic filenames have their own custom error message, MediaWiki:Titleblacklist-custom-imagename.

There is also MediaWiki:Titlewhitelist and a global title blacklist.

Only administrators, page movers and template editors can override this list on all actions. Account creators can override this list on account creations only.

ʻOkina againEdit

I just tried to move Punalu'u Beach to Punaluʻu Beach, but I hit the following filter:

  • (?!(User|Wikipedia)( talk)?:|Talk:)\P{L}*\p{Latin}.*[^\p{Latin}\P{L}].* <moveonly> # Latin + non-Latin

If I'm reading this right, this bans titles that combine Latin and non-Latin script, but only when moving. This is bizarre - ʻokina is definitely part of the Latin script for Hawaiian. I note that this subject was brought up here previously (2012) but nothing was done. Hairy Dude (talk) 02:10, 27 August 2018 (UTC)

There's also a request at WP:RM/TR to move Keaweʻopala to Keaweʻōpala over a redirect, but I can't move it because it says the redirect is on the title blacklist. Station1 (talk) 19:29, 1 September 2018 (UTC)
done; template editors and admins can do it. I suppose it might be possible to add okina to the latin characters in that regex or add it to the Mediawiki:Titlewhitelist, at-least if this comes up often enough. Galobtter (pingó mió) 19:44, 1 September 2018 (UTC)
I encountered several okina moves last month. This is a problem because it required marking for administrator attention, but the moves were eventually completed. — Frayæ (Talk/Spjall) 22:14, 1 September 2018 (UTC)

Remove the ʻOkina symbol from the pagemove prevention filter rule discussed above. — Frayæ (Talk/Spjall) 18:17, 2 September 2018 (UTC)

[V]arious apostrophe(-like) variants (’ʻ ʾ ʿ ᾿ ῾ ‘ ’ c), should generally not be used in page titles. That includes the ʻokina. — JJMC89(T·C) 20:57, 2 September 2018 (UTC)
I suggest you start a discussion at Wikipedia talk:Article titles. If there is consensus that 'okina is acceptable for article titles, then we can get the rule removed here. — Martin (MSGJ · talk) 14:43, 3 September 2018 (UTC)
The okina is widely used in article titles and there have been multiple technical requests to put the okina into titles, these were completed. Special:Permalink/855300030 is one such request. The okina is widely used in titles such as Oʻzbekiston Jumhuriyati, Oʻahu nukupuʻu, Oʻahu ʻōʻō, and others. — Frayæ (Talk/Spjall) 14:50, 3 September 2018 (UTC)
I've reactivated this request. The text quoted by JJMC89 is not definitive enough ("generally") to justify an entry in the Titleblacklist. The Titleblacklist is a "never" list, not a "discourage" list. Jo-Jo Eumerus (talk, contributions) 10:15, 2 February 2019 (UTC)
@Jo-Jo Eumerus: please specific the exact change to be made, with line numbers if possible — Martin (MSGJ · talk) 10:52, 11 February 2019 (UTC)
Seems like we want to add ʻ to MediaWiki:Titlewhitelist to make this work. Jo-Jo Eumerus (talk, contributions) 17:18, 11 February 2019 (UTC)
That wouldn't work - it'd mean exempting all articles that contain the okina from all rules; I've   Done the fix in [1]. Galobtter (pingó mió) 17:32, 11 February 2019 (UTC)

casesensitive control charactersEdit

Hi!
Why are some of the control character patterns (such as \x{00AD}) marked as casesensitive? For performance reasons? -- seth (talk) 21:10, 28 March 2019 (UTC)

Safety reasons. There have been some unexpected encounters with case-folding that prevented titles containing the letter "k", or a space, or other common things. Adding the "case sensitive" restriction means that people editing the list don't need to think about the arcana of Unicode case conversion rules. --Carnildo (talk) 02:21, 30 March 2019 (UTC)

CARIFORUM-UK Economic Partnership AgreementEdit

Hi! I'm trying to move the clumsily-named page UK-CARIFORUM (Trade Block)economic partnership to CARIFORUM-UK Economic Partnership Agreement but am unable as the title is apparently on the Titleblacklist. Could anyone help? Many thanks, Gazamp (talk) 18:32, 6 April 2019 (UTC)

It appears the first-mentioned page has been moved to draft-space so this request is moot. Stifle (talk) 13:56, 3 June 2019 (UTC)

Problem with Editor's user pagesEdit

Hello, Titleblacklist watchers,

Right now, new editor User:Love vashikaran specialist aghori baba can not edit their own user and user talk page because of a title blacklist for "*vashikaran.* # Indian astrology/magic advertising". Can I remove this element from the Titleblacklist, as long as this editor is active? It seems unfair that they can't make use of their own user pages and other editors can not leave messages for them. Liz Read! Talk! 02:40, 22 June 2019 (UTC)

Okay, now I'm confused as a regular editor has now left another message on this editor's user talk page. I don't think I understand how this title blacklist works as I'm sure I saw a pink message saying only admins and template editors could edit the page. Liz Read! Talk! 02:49, 22 June 2019 (UTC)
@Liz: you could add that specific user: page to the MediaWiki:Titlewhitelist instead of removing the entire pattern here. I haven't gone through all the logic to see if there is a bypass on user_talk for that right now, or if the namespace isn't working yet. — xaosflux Talk 03:21, 22 June 2019 (UTC)
@Liz: OK - so it looks like that pattern is only protected against creation, not editing (our local message is a bit wrong) - the talk page works because a sysop created it. I've created the userpage and usersandbox - so this will take care of the basic stuff. If they will need to create other subpages this will come up again, so you can go the whitelist route for the more specific pattern. — xaosflux Talk 03:29, 22 June 2019 (UTC)
I made the warning (MediaWiki:Titleblacklist-warning) a bit more broad as well. — xaosflux Talk 03:31, 22 June 2019 (UTC)
  • That user is blocked as an LTA (and the reason the phrase appears in the TBL). Basically spamming for love sorcery cross-wiki... CrowCaw 22:42, 22 June 2019 (UTC)
Well, I guess that takes care of that! "Love sorcery", huh? That is more interesting that our typical DJ & Marketing spammers.
Thank you, Xaosflux and Crow for responding to my query. Liz Read! Talk! 01:13, 24 June 2019 (UTC)

Protected edit request on 26 June 2019Edit

Please replace the following lines:

# The Education Program namespace is deprecated
Education Program:.*

...with the following...

# The Education Program namespace is deprecated
Education Program:.* <errmsg=Titleblacklist-Education-Program-namespace>

...In addition, please move Draft:MediaWiki:Titleblacklist-Education-Program-namespace to MediaWiki:Titleblacklist-Education-Program-namespace (without leaving a redirect). This should make an edit notice appear when someone attempts to create a page in the "Education Program:" namespace. Thanks! Steel1943 (talk) 16:31, 26 June 2019 (UTC)

Protected edit request on 22 August 2019Edit

At RfD, we came across a redirect containing a word joiner (U+2060). The redirect is Fernando Zor⁠⁠⁠⁠ ending with four copies of the word joiner. Since this non-printing character isn't on the blacklist, I request that it be added under the "OTHER UNDESIRABLE CHARACTERS" section, along with the many other non-printing characters that are not yet on the blacklist; go through b:Unicode/Character reference to find them all. (Enter "%E2%81%A0" into your URL bar to go to a title with a word joiner; the same technique works with all non-printing characters, via their UTF-8 codepoint.) –LaundryPizza03 (d) 03:52, 22 August 2019 (UTC)

  • P.S. I think this will require a custom warning message. –LaundryPizza03 (d) 03:54, 22 August 2019 (UTC)
  Not done as to the immediate edit request, discussion can certainly continue below, including dealing with the need to build any custom messages in support. — xaosflux Talk 13:42, 8 September 2019 (UTC)
