Often cheaters aren't good enough to beat players by themselves, looks like this was a person who could beat the players even without cheating, only used it to even make more money.
Also reporting them even when you know they did something wrong is sometimes hard to do, cause in an experience I had I tought I "knew'' someone well and when I tought we still were "buddies'' he even told me what he was doing and how he was doing it. We basically did get less close with eachother the period after to basically not like eachother anymore right now, but still it would have feeled like me ratting him out, altough it would have been the honest thing to do. The player in question got his accounts locked eventually , I even saw him multiaccounting a 15 player league (with $500 and 1k tickets on top for playing 4 games with points on both PS and FT) which was basically one of last signs on Rational Group pokersites, guess their security finally found out.
(feels good to get this of my chest tbh)
