About once every month for some reason I start kicking ass. On MW2 on afgan I was sniping and for two clips every shot I got was a one hit kill. Also just this morning on mw2 I killed a guy, picked up the grenade he dropped killed another guy with it, then knifed 3 guys in quick succession and finally stuck a guy with a grenade when I was in last stand. All of this in about 10 seconds. But to answer your question no I have never been banned
