Heh, something really needs to be done to curb this. At the rate they're going, they're going to fill up your server space before the year is up. :p Not to mention the server resources they are needlessly taking up.
Anyway, I've temporarily removed all of the spam off of most of the pages of the wiki (and by temporary I mean till the bots add more crap back in).
Something more permanent needs to be done, however. To stop and new ones from registering, I would recommend
reCAPTCHA, this is the one MediaWiki seems to recommend, and the one that the ZDoom wiki currently employs, I believe. It would stop the vast majority of them from signing up.
As for what to do with the ones that are already there, well, I have no idea. I
do know that
something needs to be done, though.
