I wasnt cheating, I just got banned on the deathmatch server(just connected and got banned),and when disconnected,I tried to connect on sniper and some other server(also your one server),and saw Banned permanently white letters on the screen and when tried to ask what is happenning, it kicked me with message Not allowed!
I dont know what to do. I hope root admin will understand me,and unban me because I am really telling you the truth.

edit: I dont know why would I use hacks when I just downloaded game to see how it looks and to play with friends.. I can swear that I didnt hack
