KYC isn't mandatory on registration, the only personal information they require is your date of birth. The KYC part will depend on your gambling activity like having big deposits and withdrawals(above $2,000) or breaking the T&C.
As you claim to be a KYC expert, can you quote the gaming licenses regulation in regard to KYC?
Our gaming licenses (both in the UK and Curacao), regulate that we must undertake a Know Your Customer process (KYC) which enables us to establish your identity and location.
