The thing is that even if it’s a tactic to reduce underaged people from accessing gambling sites, we all know that it’s not going to be 100% effective because there are lots of other gambling sites on the internet that doesn’t even require you to verify your identity before you can start using them - if those people should learn that this whole selfie thing is a means to get them to leave gambling, they’ll simply just take their things and switch to a more friendly place.
No KYC casinos are rare even if we don't have mandatory KYC still they can ask for verification at any time so user who register must be ready to do it and I know a few legit casinos that operate and require no casinos but those have very limited games or even just dedicated for one game.
It sure would remove those who are just starting out gambling newly, but for those who have managed to become addicted to it, it won’t work since that urge would drive them to look for a different means to access gambling.
Not to get addicted is ultimately in the hands of the user, the casino can do only things that they are in their control and they are also here to make profits.
