As for your other question, KYC is not required for playing and registering, however it is a MUST if you withdraw funds. If you attempt to withdraw without being verified, you will be notified about it.
So KYC is mandatory. You can't say it's not, don't you think people are just depositing and play without any withdrawals?
Just say KYC is needed in order for the player to play and withdraw the account balance.
Pretty good website though, I see it improved.
Therefore, before you register at a casino, you should read the rules very carefully. It is clearly stated in the terms and conditions that KYC is required for withdrawal. The truth is, if someone does not read the rules, he can blame only themselves.
