I understand the challenge with submitting KYC to untrusted platforms but the truth is that the advantages of playing in a casino that request for KYC during registration is higher than those that does not require KYC
Why would someone submit his personal documents to an untrusted platform! You should not even play there, let alone entrusting them with your personal information.
There have been countless cases of people losing significant income due to casinos requesting KYC after winning; I consider this a deliberate attempt to steal people's fund.
The problem is not with the KYC requirement itself. The problem is with shady/scam service providers (ab)using it as an excuse to seize customers' funds.
