I would always choose a casino that performs KYC anyway, it means they don't cheat their players
I don't quite see that relationship. I agree that most casinos that ask for KYC are legitimate, but nothing prevents a shady casino from asking for KYC, scamming you and then selling your data on the deep web or somewhere.
If the casino wanted to get scammed and not pay the players, it would have done it a long time ago. And the casino has been working since 2013. It is better to solve all KYC issues in casino support, and here it is unclear whether casino representatives read the thread and whether they know about the problem.
