But, if the casino refuses to transfer the winnings to the player’s account due to the fact that he cannot confirm his identity (this can be for various reasons, including justified preservation of the player’s safety) and cannot pass KYC, then an appeal to the regulator  such a player cannot do either.  This is simply due to the fact that no government authority considers appeals from anonymous persons.  And for the same reasons it is impossible to go to court.  This creates a vicious circle.  And the player can only either stop being anonymous, or lose the money that he honestly won in the casino. 

I reason that the authorities need to come up with some guarantees for such players to receive fair winnings.  And at the same time, at the request of the player, remain anonymous.
