my reason only data security and complicated,
I don't gamble too often, so I don't feel I need a casino site that needs KYC,
there are now many good casino sites that don't require KYC,
so, don't mind the casino that requires KYC.
There are incidents that a non KYC casino would require you to pass it when you are about to withdraw. If they suspect you base on the history of your activity within their casino, they have the rights to do it.
I usually try to avoid KYC casinos, but there are sometimes require to have a process like this one.
There are a lot of people who abuse faucets and rewards which is a loss for the casino, so there should be some measurement that can eliminate those abuses.
Yes, there are times that they have to do but it's mostly to special cases and incidents for which to verify the user.
Right, those activities that would be against their terms of usage and agreement, that's the solution that they have to implement.
