All of these supposedly statistically fair games seem to rape you when you cash anything out or just when you decide to bet bigger than some micro level.
Curious if anyone has ever beat one without getting crushed the second they take some off the table?
I don't really understand your question here how could they rape you when you are already cashing out?
People have a reason to believe the site owners or game operator cheated when the game result seems to be switched and when the site owner doesn't provide the adequate seed with a link to verify the algorithms of each game. However, the OP makes a good point cause some provably fair site does cheat but I will advise him to always check the fairness information site before using it.
If he really cares about his bet, I am sure he will always check the provably fair, but if he only bet without thinking much about provably fair, I think he will play the game. But if the reputable gambling site really cheats their members, I am sure that it will take too long to see their reputations will ruin because of that. I am sure that the gambling site will not play with that because they concern about their members and their website.
