Thread:Project:Support desk/Unauthorized Users

I'm running MediaWiki 1.19.2 with PHP 5.2.17 and MySQL 5.1.53.

I thought I had set up my wiki that users could not be automatically created. I found out last night that I didn't. I have fixed it since. But now I have 7400 unauthorized spammers on my wiki. They haven't created any content pages, just user pages.

I cannot find anything to where I can remove the users en massefrom the Special Pages. Is there an automated system to do this? If not, is there an easy way to do it?

I can't find anything in the MediaWiki help in removing the members without having to do it for each of the 7400 individually. Any help out there for me?
