I do not understand why I got a ban.

I play without strangers software. Kick with the server with the reason "you were excluded by the administrator"

I play badly, but I also got a ban.

on one server wrote to the chat that I use the aimbot, but it is not.

throws out with the server with the protection of the fairfight. and with punkbuster everything is fine.
