Also if you look at the account setting, we don't see a "KYC Option" at there. So i think BSpin don't need a KYC went using their casino.
So how do they handle this promotion? I or any person can benefit from promotions repeatedly by opening multiple memberships. Doesn't that look right?
Most of the gambling websites are working without any need for KYC. As there are many websites, if a website require users to pass KYC, be sure no user will use that websites. Because there are many other options. Gambling website are trying hard to win the difficult competition with several other gambling websites. Making KYC compulsory is equal to losing the competition.
By the way Which promotion are you talking about? Do you mean misusing referral links?
