Automatically Refuse Spam Users
From WinWolf3D/WDC
For MediaWiki 1.5.2.
If you block guest users from editing pages, spammers will start making junk user accounts. Luckily their usernames follow some patterns. This code will cause user names that match the patterns to be automatically blocked upon creation.
