They say that they can ask for KYC if they believe a player is underaged. How could a casino suspect that based on a player's betting pattern.
Another thing I found interesting about them is that they don't have a betting license, however, they do have certain restricted locations. I wonder why that is!?It is positive though that they will not confiscate your coins even if you refuse their KYC demands.
I'm also wondering how the system will suspect the underage users. Maybe they will observe the betting patterns. They may contact the user if they find it unusual than all other bettors. And it isn't so hard to determine an underage person by doing some conversation with them.
Probably they still have some restricted countries as they had license before. Some countries have strict laws against gambling. It could be a reason to keep the restrictions on some countries as well.
You didn't add any sources for Roobet and FreeBitco. Links are missing only for those two casinos.
Freebitco have the shortest list of terms among all gambling site. They have no single word about the KYC/identity/AML policy in their TOS. I found no information there which could be included in the post. About Roobet, they have mandatory level 1 KYC verification system. I didn't include any more info in their KYC requirements column as they have a mandatory verification system.
I believe Curacao eGaming has a license validator, but I'm not sure about the others. Perhaps you can post an example of a gambling site with no license verification here so the community can help.
The license validator logo is not available on some of the casino that you listed on the table. I don't want to mention specific casino on your list but there really is.
Almost every licensed casino have the validator link available at the bottom of the page. I found only 2 casinos from the current table who have license information available at the site without validator link. One of them is Betcoin.ag and the other one is CryptoGames. @Beparanf, it would have been more helpful if you had mentioned the names as well. I have sent a message to both casino email support for the details of license validator. Let's wait for the response of them.
