Yeah, mantis1988 is totally right! This guy is just a troll. Picture on the monitor in first seconds of this video shows GamerSuper faces with a writing above it "Your master" (or lord, or overlord, I don't know english very much, but I think you get the point).
After watching the video, I dunno I just felt angry, him showing his picture, and then constantly repeating that he was the first to do this. He just came off as a bit egotistical, I just don't like that kind of personality.
Whether this method is legit, I'll leave that to the experts to decide.
