This is kind of scary. One has to wonder if there are other folks around the world who might be doing something similar with the help of staff and due to being more careful (and not live streaming) they are not being caught.
And even if there aren't others, what about the perception? This story has gone fairly viral, how many players are going to be scared to potentially play at all out of the fear that they could get cheated by a superuser such as this? Not to mention all the weak players who might suddenly claim that they only lost in the past because they were probably playing vs some superuser and refuse to keep playing as a result.
I know when this happened online all those years ago (Ultimate Bet) that was the immediate reaction from many "ohh that's why I lost online all those times, I was being cheated" even when it wasn't true, just a convenient way to explain away a lack of skill. So yes feels very dangerous in general.
