StarDestroyer.Net BBS

I'm starting to see new accounts show up on the wiki that post links to things like research papers sites. I figure their bots, and I undo their changes and block the accounts. I was just wondering if anyone knows of any updates to the wiki software that we should be looking at using to try to block this kind of activity in advance.

Use mass blacklisting

Alternately, you can take care of most of them by checking for an open port 80 on registration. Make such people contact you to get an account.
