Running hs is already almost impossible, but it is far range, with a smoke and he does a perfectly smooth 1ms flick on the head. I mean, it is possible because everything is possible, but that's so highly improbable that it can't be anything else than cheats.
Once again, Valve didn't clear his account, Valve cleared him from the allegations saying some VAC accounts belonged to him.
