banning problem

Hi

I got banned like 3-4 times after a really short time while I never know why. The only things I do on MPGH is getting cod hacks and posting some messages for help or support other people. I always receive the message my IP adress got banned and I can contact the administrator by clicking here.. but it never answer so I ask it here.. is it a problem with the site I always get banned or?? cause it annoys me last time
