They should advertise themselves as a minimal KYC crypto casino instead.
Gamblers don't like being lied to especially since they are risking their funds which is why they appreciate casinos that are transparent.
Is that even matters? everytime a new player register an account, they will need to check the tickbox for the T&S therefore its pretty much their own fault for not reading the terms. You will be asked to fill in level 1 KYC right off the bat so if a player doesnt want to risk any of his identity then he can simply choose not to play in Roobet, its as simple as that though
