Terms are changing from time to time including about KYC related thing.
These days, KYC seems to be something very common in this gambling industry due to license and regulation.
Unlike what we can see several years back when crypto gambling industry is still in the beginning stage as well as on the other crypto industry such as exchanges.
Regarding KYC, always ask the support first so we can be sure about the rule in the casino.
I think we all have noticed that change, years ago being able to gamble without going through any form of KYC was pretty much a given in most casinos, however since then governments have pressured all kind of centralized entities to try to identify their clients, they claims this is done to reduce crimes but we know that what they really want is to identify how big are your holdings, and if they can to tax those holdings and try to get a cut from the money you have been saving in bitcoin for years.
and in response to what panjul said, one can always check the terms of the site in terms of kyc. but if it is not yet clear to you and want to confirm the kyc related stuffs, yes, you can contact the support. at least it is coming from their end.
but if you are a player who is very careful, you should always browse their ToS before anything else. because usually, player will only read it after they incurred a violation and their funds are put on hold.
a lot of accusations are rooting from the player's violation of ToS and not from the site's end.
The KYC policies of casinos are on their TOS so it is important to read them, however we must be honest if you are gambling in several different casinos then it is not going to be rare that you receive some updates regarding the TOS and it is going to be difficult to read them all, so while in theory a player must always read the TOS before playing at a casino and after every single update, most of the time this is something that is not realistic to do.
