Aside having a government license of operating a casino the owner might be inflencial that makes him overlook some of the rules and maybe they have agreement with the licencing company that permit them to allow client to register without KYC which is mandatory for clients security purposes not for the casino owner but personal interest. I have only experienced no KYC on new casino sites with the believe that it was a tactics to get more clients to on their platform whether they are government owned or private.
Agreement is what you do when coming out for a business or trying to network with others persons.
KYC is hardly a problem for many. A lot of gamblers keep at it today, gambling even with the requirement of KYC. It’s more about a government problem with the casino than a registry problem. You can get licenses from a number of places but, compliance with local laws ensure you aren’t using your casino for wrong reasons.
