Indeed, especially if you are faking a government issued ID, that's punishable by law.
There's nothing thy can do if they are not allowed to gamble, as long as there's a low prohibiting them, they should follow or face the consequences.
The best option is to gamble in crypto, use VPN, and gamble on sites that does not require KYC.
IMO, this can be done though risky at the same time also on your end.
