G-Master[K] noob at gm?

It was 2 vs 2 ghost mode i was started to play using shift as a walk(u can hear better stupid breath of ghost if u have a good headphones) i was making pwnage with p90 and after that they cryd that i hack.I dont get it i m not a hacker i never used any hackz in mylife and they calling me a hacker.That is just stupid.I was respecting him because i saw him many times in action and he was like a pro.Now he says that i will be bannd because i was "using hackz" and that i will say bb to my acc -.- its a shame but i never heard from any pro players that they acting like a noobs.pff.
