Each gambler must read TOS first. This is needed to avoid possible problem in the future. If they don't want to do KYC, they can choose casinos with a free KYC. However, I assume most casinos will apply KYC as one of the requirement to use their service. CMIIW
Many gamblers are not interested and not ready to read Tos of the casino and it is when they are caught on the net and having problem in the casino then they would be coming here to accused the casino. Another thing I am also thinking of is that casino should make a possible way for gamblers to read the necessary things of the ToS. Such as KYC, deposit and withdrawal, supported countries should be displayed on the home page, sign up page and sign in page.
