I saw that crap this morning. There were 3 of them total, although 2 of them posted 98% of the shit. Its moments like that that would have been nice to be able to reach through the screen and slap someone. Not sure why they pick the places they do ... but it looks like we need to come up with a more limited access.
I found a forum once that asked a few game related questions to be allowed to join. It would probably help weed out a lot of the spammers.
