That video is a fraud as far as I can tell. Playing cs in high elo's is more than 50% of the matches with cheaters. I played with a team of cheaters one time that was even blackmailing the opposing team for real money, and they got it, and blackmailed again, than they disabled cheats. This is a whole industry. That was one of the last times I played. I actually encountered the same cheaters a few days later.
