Banning a problem user

[DaveG]

Thanks for the replies... This guy was given the miserable hack and then he logged out. Once that happened he was back in business and setup a new userID. Every time I would try banning the user, he would come back with a new IP and a new user account.

So... I was able to track all this as I was online at the same time. New account, post ban him. Then he would keep doing this over and over.

Finally, he apologized and I reinstated his main account. But this punk is going to start trouble again so I'm not sure what to do.
I can't be too restrictive with an IP ban because I don't want to block all the other people within his ISP in the area (actually, I did that by mistake for about 10 mins).

I was lucky to be online at the same time he was, so I was able to track everything and his other IDs as he created them. But in the future when I'm not online to catch this, ugh. It can be a mess!

Oh, and when I emailed his ISP about this, wonderfull good `ol SBC global wouldn't help. All they were interested in was email abuse and SPAM.
