Thanks for your answer dude!
Ok, so making sure I ban the addresses this guy logs on is the only way...
Doesn't this guy have an infinite (just a guess) amount of IP addresses he can log on from?
And, by banning the ip's that appear on my server, won't that maybe, possibly, affect a regular user, with that ip address from logging on to the stream?
Sorry for questions, have no idea how proxy works...
