Well, as you can see in my signiture, we have a forum for our small linkshell community in FFXI. It is a great linkshell.

Lately, we've had a problem with a member who decided to leave, steal and be an immature bastard to most of our members. And now he's deciding to troll our forums.

We've blocked his IP address, but he got in again, so we blocked it again. But now we're not really sure how to go about keeping him out?

It's just an invision-free forum though, so I don't know if we're limited to something like this. We do know that he has a comcast IP, and were thinking of contacting his ISP and seeing if they can help us out to stop him.

Please help. ^^
