Fraud cases are becoming a real problem for gambling industry, from schemes like bonus hunting, account farming, account hijacks and illicit chargebacks on the rise I believe that many new casinos aren't prepared for the menace ahead.
Some casinos still believe that not asking for KYC is cool, but it's actually not, I see casinos with no kyc as a red flag because you can't run your business this way without getting into trouble with regulators.
Casinos neglect identity check but little did they know that they can be fined for it, if fraud cases arise from your casino and it's been investigated, your business is going away soon or you pay up for fine. One, for failing to screen customers using the KYC process, two, for possible running of unregistered casino.
Do you think your casino can be regulated without the AML policy? The requirements says it's all, so is it possible that those casinos doing their no KYC stuffs are not even registered?
Sometimes they are playing with words. I have visited some casinos that claim to be no KYC, usually have conversation with their customer support representatives to confirm things but then they say that they may ask for KYC if there is something wrong. I.E. some of them call themselves no KYC because they don't ask you for KYC to play but they still may request KYC documents from you if they think there is something suspicious with you.
But there are also some casinos that don't really ask for KYC. These casinos are usually small and not so comfortable to use. In this case, if you risk to use such casino, you should keep in mind that it's risky but also you should keep in mind to lean towards the one that has highest trust in this community.
