That is good practice for someone who gamble regularly on such platform, that's why you have to chose and make research first before providing them your KYC info because there are lots of casinos here already. Descent casinos marketing's offer free spins from contests here, competition from multiplier, price prediction, etc. which needs registration when you win or to participate. If you keep that practice without any kind of conditions and etc. you will end up providing your info to lots if casinos. Some of us here don't bother to provide their info, as it's like just a couple of requirements and docs to any casinos out there.
