Agree with the post from Slow death, from what I knew all of the licensed online casino operators are require to conduct a KYC to prevent underage gambling , local AML regulations, online fraud, etc.

Maybe it will be better to write that the site only require a KYC when necessary and legit user doesnt need to worry about it.
The statement will bring pros and cons, however that is better than write No KYC at all while the terms said the otherwise.
