Actually sticking to their own written terms is better than stating a different statement here in this forum, simply say that KYC can be asked anytime, I'm sure most gamblers are understanding it really well these days.
No need to promise KYC free because I believe it does not exist anymore unless it is a fully decentralized casino.
As a gambler, the point that you mention is highly acceptable as I knew already what’s the AML rules set on casino so they really have no choice than to obey instead of declaring a total anonymous crypto casino in the forum.
Most of the user here is already well versed on casino ToS and already accepted the fact of imminent KYC. I think they don’t need to push this tag line here since gambler will keep playing on the casino regardless of the KYC requirements if their promotion is good.
