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?
In a no KYC zone casino and other betting platforms, there will always be high risk of fraud but it doesn't mean that because KYC are been requested will stop fraud and scams from players, there will always be some guys that will stop fraud thing even if there is detective that guard the casino, even in physical base casino where people represent each one or one is full of players that do cheat their win to win, its a normal thing for every casino to have cheaters only that KYC is one of the ways you can reduce them.
Other than that, there are other techniques Casino does use to catch cheaters in the casino, I have experience some cases in reputation board where two verify accounts are reported of been related from their activity and the IP address also reveal the same location about the two of them and after much investigations was carried out, the casino investigation team shows eveident that the account belong to the same person, so you see that KYC is not to prevent fraud from happening right.
With all these, KYC is not enough to prevent all this cheating you mentioned but it can reduced it actually but then again, are we going to be giving out our privacy because of their own interest, just because player X is cheating don't mean Player Y will do the same, if it is about the bonuses, I don't think its all the player that want the bonus in the first place because of the condition that comes with it.
