I still don't understand why someone has to sign message to get his money back from gambling site.
Player come to site, make deposit, lose money -> nothing happens.
Player wins money -> Breaking TOS. Private information. KYC. Signing messages. Scam accusation. Drama.
I know it sucks but it is how it works even on regular FIAT website, you can create an account make a deposit and lose money in minutes, but if you win the KYC will start.
