This guy Gaint11 is running around hacking servers. He has hit 14 in the last 2 days. He's part of the |[< BLACK PREDATORZZ >]| Clan here on gametrackers. Gameservers told me to come here to file the complaint and that someone from gametrackers would take care of it.
I have another guy from overseas that pm'ed me with the same problem from the same guys. Please help or point me in the right direction so I can file a formal complaint.
Btw JPF My clan owns the #1 Black Op's In the world and If that one get's hacked I'm gonna be one pissed off dude.
the link to there page on gametracker is here http://www.gametracker.com/clan/predatorzz/
Thanks for your help.

Not sure what you mean by "hacking servers". For the most part Gametracker.com doesn't host or administer servers, we only collect stats.

Hacked the server meaning he Claimed them, changed the name,changed the locations to Pakistan and changed the gametype. His account was suspended here at gametrackers and now Gaint11 is now Gaint111. So nothing is really being done about this? He hit 14 servers in 2 days.
Gameservers rep told me to come here to have this issue resolved.

Yup the same thing happened with us and the same clan,there claiming ownership of the server,dunno how they do it but it needs to be sorted!! it's getting ridiculous. We were all like wtf! pakistan? presatorzz clan! So we had to do a complete reinstall of the server and just kept trying to claimownership again,eventually it worked but this needs sorting out asap!!!
