I've noticed that Wikipedia and Meta have a spam blacklist that disallows external links that match certain regexps. How do I enable this on my local Wiki?
I've tried setting up a page Spam_blacklist, copied from the version on Meta. I've searched for information both on Meta, and by grepping the php code.
I'm currently running MediaWiki version 1.3.10, but I grepped the sources in 1.4.2.
All help appreciated,
Charles
