Sue him or her and make sure the isp that the person is using bans him or her from their service all the person is banned from using the internet..lol...haha..
Lol they posted their calling card. The guys at [Only registered and activated users can see links. ] did it because they hate sites about gaming and/or hacking games. And don't think they're going to give two craps if you post your opinion on their forum :D
While this is all fine and dandy, why would a HACKING site go to court? You really think any sympathy would be given to a bunch of people bent on hacking other games? Here's the courtroom:
GzP: "Yeah, these guys hacked our hacking site."
Judge: "Hacking site?"
GzP :"Yes, we have many talented hackers who hack online games and destroy the purpose of actually trying for many others who do not hack. Can you put this guy in jail now?"
