Many online casinos, just like yours, don't require KYC immediately after a player signs up. However, the platform reserves the right to request identity verification if and when it sees fit. Point 17 of your T&Cs explain this. The casino can ask you to provide identifiable information to them or a third party if necessary to verify your identity or for any other reason. I am sure that happens, and I am also sure scammers will abuse your service if you didn't do it. So, it's a double-edged sword.
