I don’t think any registered casino platform would hide their policies from users, however, if they should ask for KYC Which was not originally part of their policies, then I think you should just go ahead to provide them with the details they’re requesting for.
sometimes they can twick the terms and conditions so that we may not have full understanding about what it entails. We just need to be more careful about casinos like that if we find something fishy that looks like we might not seems to understand the when details of what we have read. It is good to do our own diligence for a better choice.
or better yet, if you are confused with their statements under their terms, why not contact their technical support and clarify about your doubts? because if there's a complaint on the casino, they will surely refer to their published terms and conditions. because if it is not found on their terms, you can very well protest your case. they don't have anything against you because where will they get the valid reason why they won't be resolving your case?
We casinos would idea the vital information in there terms in a way that we might not understand and at the end that will use it to fight us so we can quickly blackout. There are many ways casinos can win us in this kind of game especially if there intention is to take away our money illegally.
