http://meta.wikimedia.org/wiki/SpamBlacklist_extension can be made to
use Wikimedia's spam blacklist or one from any other MediaWiki site.
It's best to use it in conjunction with the spam whitelist in case
Wikimedia are blocking sites you don't think need to be blocked.
For blocking IPs and usernames across wikis, Wikia have developed
RegexBlock. See
http://www.mediawiki.org/wiki/Extension:RegexBlock
There is also Wikia's SpamRegex which is useful for blocking non-URL
spam. See
