I see a LOT of possible bots in the Stake Poker rooms, especially in the freeroll tournament. People that don't make a decision, time runs out, they get sit out and then after an exact amount of time, jump right back in. I sat next to one of these "people" in a freeroll tournament and intentionally played them out - let the cards deal fully on the table and see what they have, and one of those times they had a massive win over my hand, yet no bets, no raises - nothing. Then immediately do the same thing again, timing out a preflop and jumping right back in.
Secondly, there are users who join all the ring game tables. Now that's pretty normal, online poker environment allows one to do that, but I am seeing these people winning absolutely unbelievable hands CONSTANTLY. I understand the nature of Poker is that there are a lot of variance, but to watch these players sit at their tables and win consecutive hands after hands after hands, getting dealt turns and rivers that heat them up and cool others off so they win all the time (and yes I checked - even marked their profiles to see if they're the same person winning over a period of DAYS), makes me question - does Stake have their own poker bots to fill up the tables? And then to go look for the provable fairness of the Poker games, only to see it is nowhere to be found.
