They do exist, they just usually "forget" to do KYC when it is convenient for them, aka when people deposit. Then, when things go sour, they request because (insert reason).
I have seen crypto brands who do not do it for a while after launch and then change policies. Keep in mind the casinos decide whether or not they conduct KYC, licence authorities like Anjouan and Curacao probably never (I would wager a bet) check their books, audits are just words in the terms and conditions.
MGA and UKGC casinos must report source of wealth, I have experienced both personally, or else they will just block your account. This never happened on my favourite Curacao casino (Chipstars), which asked me for KYC once and never again, even after I have deposited much more than the UK maximum deposit limit.
Chose something in the middle, mate.
