Im not sure exactly how they work. Im assuming its a bot honestly, but what they seem to do is find a forum, somehow script their way through the regestration process, and then post the same crap over and over again in random forums.
Ever see a forum or picture hosting place that, as a verification key to continue, puts up a PICTURE of a word? A script can't scan a picture, but it an scan for text. The picture of a word i think is one methord of trying to break the bot's scripted process, but this is conjecture on my part.
I remember though, they had to shut down new user regestration, and i think every friday the site owner would open it up again, and place bets as to how fast the bot would regester a new user account and place more spam.
Think of a form spam bot in the same way your email address gets into a spam list. Its basically the same thing, only instead of just spaming your inbox, it spams a forum.
Neal can try and ban the IP, or change the regestration process somehow. Only problem with IP banning is that whoever is responsibe for the bots, probably has a series of IP's to use. Not just a single C series, but a wide range of IP's. Many people who get infected with spyware or adware become unwilling hosts, with their machines launching "attacks" and not even be aware of it.
