I'm not allowed in, but good luck with your business. Not going to risk it with a VPN.
Out of curiosity, if you allow VPN use, how are you going to know if the account got stolen or not? Casinos usually don't allow people to use these services because it allows them to monitor the IPs and lock withdrawals if they're made from a different location than the one a player registered from. This may become an issue for you later on.
I am not even worried about stolen account. What i suspect might happen with VPN usage is abuse of bonuses and multi-accounting, and maybe playing from restricted Jurisdictions. How Richy.casino is going to curb some abuses? I don't know, but it's going to be full of chaos. We shall have even innocent users getting accused of having multiple accounts.

If they take too long to sort you out, then you might wanna think about opening up a scam accusation in the dedicated board.
That was smart of you, because there isn't a direct scam, just technical issues. But it should be right here. People should know that the casino doesn't work properly and doesn't have money for developer team (pretty sure that the founder is only one developer there). Just a good neighbor advice to those who planning dep in your casino more than 200 usdt.
