MediaWiki:Titleblacklist

# This is a title blacklist; titles that match regex here are forbidden, and cannot be created.
# Use "#" for comments.
# This is a disallowed titles list. Titles and usernames that match a regular expression here cannot be created.
# This is case-insensitive by default
# Options exist to stop editing and moves as well.  See mw:Extension:Title Blacklist for documentation
# See the talk page for more information.
# Please note <newaccountonly> is no longer useful locally as accounts are created globally, these would need to be added to the global blacklist.
# Please comment any additions made to the blacklist.
# Note: Internally, the pattern delimiter is '/', so be sure to escape all '/'s.
# UTF-8 mode is enabled. Do not use literal non-breaking spaces in regexes as some browsers cannot handle them.

# Block all user accounts, and only permit those that match the MediaWiki:Titlewhitelistregex 
#.* <newaccountonly>
#.* <autoconfirmed> # Stop everything
