What I hate is they keep signing up new members. I have a private board for personal friends, but these spammers just keep joining and registering new names. They can't even post on my board because I've disallow any new members without admin ok to post. Yet these robots are just registering new names, and I get 30 emails a day trying to get permission to join the site. Forget trying to ban email or ip, they are just generating them with a robot.

I can only imagine the nightmare trying to stop them with a public site like this.
