Some guy called Marcel. He had an accuracy of 172% with smg and a ratio of about 7. I performed some experiments to check if he was aimbotting, such as sneaking behind him. He would snap around and shoot me dead with 1 shot, using smg.
Other people on the server claimed he was actually somebody called wizard of oz.
My team tried to votekick him numerous times but the other team were reluctant, presumably because he was a good asset.
