It's the datamining sites I was talking about. They've always been there as far as I know, I used one in 2004, and online poker has done ok so they can't be that deletrious.
If some grinder berates a fish using data they got from one of these then a site should be happy to ban their ass, not just chat ban. One warning then close their account. That's the way to tackle to problem imo as closing the door for datamining also closes the door to anyone wanting to verify the integrity of the RNG.
Correct me if I wrong but the older sites like sharkscope only let you know results, whereas PTR tells you every statistic (VPIP/3bet % etc etc) a player has and thats where the real problem lies, not only is this site telling you who the losers are they are also providing you with a blueprint on how best to exploit them.
I agree with what you say about the RNG, it is good that people can independently monitor stuff like that, but what PTR are doing is killing cash games.
