Look how gambler friendy stake is, they let the player get fucked just because the odds provider doesn't want to pay the bet
Do you have some proof to accuse stake? I guess stake is one of the most reputed casinos out there; I'm on it & had no problem either. But it's also possible that they are selectively scamming people. Can you create a thread on scam accusations by presenting all the documents instead of sharing them here? That would be great to have a look at.
Let the guy give proofs. Why should he go and create other thread while he can post everything here? If he has 100% proof of being scammed, I think it would be useful to others to see this information. But only if he has something to show us. If not, I think it is a good idea to deduct a bunch of his trust:)
