I do not see how pokerstrategy could be to blame in anyway for this guy cheating (if ofc this is proved)
I think the real issue is online poker and its reputation, I was chatting to my boss a couple of days ago about online poker as he likes playing live, he told me his biggest worry about playing online was people colluding.
Every time the public read about this kind of stuff it tarnishes the game.
If the ordinary man on the street starts to think online poker is fixed, then they will stop playing and find other ways to entertain themselves.
