I saw some topics where some gamblers complaind on how they were locked out of their accounts by the casino and they lost their funds because they could not gain access to the casino again. For cases that was not the gamblers fault, the casino treated the problem and unlocked the account of that gambler, while for those gamblers that was at fault by violating the rules and regulations of the casino, their accounts was never opened by the casino and the gamblers lost their money for ever to that casino. Still on the case, if the punishment of accounts blocking is the price that ignoramus and stubborn gamblers has to pay, what does the casino do with such money after then? Do they convert the money for themselves or they have an authority they pay such money to?
What the casino do with the money later is none of my business, I don't even want to know, the problem is with gamblers who can't follow simple instructions, they deserve what they get.
The casinos are always in need of money, they can use such money to fund their casinos campaigns and advertisements.
If you can't read the terms and conditions then don't do anything stupid, be ready to pass KYC verification at any time and don't try to use multiple accounts on the same casino, since I've been gambling I've never get locked out of any online casinos.
