Fuck me, they're everywhere!
I think the annonymous posting feature needs to be tightened up a bit to make it more difficult for these spambots to get on. I don't mean get rid of it completely. I just mean have another method of doing it as the question one is being easily bypassed.
Plus these spambot posts make the forum look cheap and abandoned (more than usual, I mean). Bastard spammers! I hope they all catch some nad shrivelling disease!
