Player11 (UK) was on what I think to be Ping laming on purpose, He was almost impossible to hit since he would appear and disappeared constantly.
Another player told he was like that yesterday and using the nick Cant Sleep, I left to Spec him and even though is Ping said 140-180 (800 sometimes) no one with Ping 140-180 plays like that, I have that ping on the US server and I dont screen jerk around appearing and disappearing:

To me its obvious he was using the Ping (or whatever he was doing) as an advantage since he knew it was basically unhittable, so he grabbed and capped at will.
