Hi @Andy-Unibet,
Thank you for taking the time to look into this. I've been playing sit&go and spin&go/hexapro games for more than 6-7 years, over multiple networks, and this kind of behaviour has happened/ it's still happening in other places too, and I can firmly state that it is impossible for these players to start and finish their sessions without any agreement between them. There have been multiple times when games where available, with recreational players around, these players stopped because a couple of other honest regulars (including myself) were playing at the same time and it wasn't profitable for them to continue. For the sake of the argument I'll give you an example, which I can prove with the hand history from my account: last week, during one evening, there were 11-25 players according to the Hexapro lobby. I opened a couple of tables, these 2 regs were playing plus one recreational. After 10-11 games, both of the regs went away, at the same time. I stopped as well, just to the test the story, if they would come back once I left. And 15-20 mins later, whilst I didn't register at any 100's games, there were 11-25 players again. I registered back, and guess what, these 2 regs were playing again at the same tables. With all due respect, you cannot tell me this kind of situation is just a coincidence, or they took an accidental brake together and came back at the same time, because I've been for too long in the game and I know it's not. Also, I won't argue the fact that this feature of how many players are at the Hexapro games is misleading, that is another story, which maybe at one certain point you guys would like to address.
@Groggy Your math is quite good, but I would say that the rakeback deal is very important in this equation . These regs are very good, so together they make much more than 20% ITM when they play at the same tables. This kind of scheme works on 3 handed games quite good when 2 players share their profits and losses(to minimise the influence of variance, e.g. 1st reg wins 15k profit, 2nd one loses 5k; which results in a combined profit of 10k, 5k each), and a big profit margin comes from a good rakeback system, such as the one present at the moment on Unibet. At 6-7 million points, the rake back is close to 55-58%, according to the current challenge system, close to 40k per 3 months. @Andy-Unibet I'm convinced these players make more than 7 mil points on a permanent basis, and withdraw quite often their profits, so the don't loss much in case they get their account locked.
Multiple sites took action against this kind of team play, and I know poker players that have been affected by unethical play, and have been compensated.
