Content Banning Blacklists
To prevent a spammer from saving wiki edits with problematic content, use the variable $wgSpamBlacklist. This should contain a regex for matching on any URLs (or parts of URLS) which you do not want to allow users to link to.

There is also SpamBlacklist_extension(which has a patch for v1.5) extension that makes it easier to manage the regexes and collaborate with other sites.'''
