Retaliation is likely not the smart thing to do here (remember, he got you once, next time he might be destructive). I recommend, if you have had enough of the little bugger, put in a firewall rule to completely drop his IP ( or the whole subnet if you want). Take a small snapshot of your firewall log and send it off to [email protected] and let them take care of him. You have got enough to do just cleaning up his mess.

Good Luck.
