Alright so I'm a moderator on another forum at the minute and as part of it's growth in its early stages, we need to keep it clean of bots. Y'know, the annoying Russian viagra spam kind.

There's email verification and captcha in place yet still an irritating number are slipping through the cracks and causing the place to look messy. They're being removed and banned quickly but I've noticed that other forums don't seem to have, or have solved this problem long ago, stopping them from ever existing as anything else but guests that can't post.

I'm still learning forum stuff so I'm not particularly experienced but does anyone know of better ways to deal with them? Preferably a more permanent solution. The forum is run on vBulletin, by the way.

Cheers.
