I still maintain my point that, the casino has a very huge role to play in the regulation of underaged gambling and that’s if they will be very sincere with their KYC terms and policies.
Most casinos avoid KYC not because they want to attract kids to their sites but to allow gamblers to gamble with privacy. KYC is often disliked by the ones who prioritize privacy and that's why some casinos allow everyone to gamble without asking for any KYC details.
You are correct, most gamblers don't feel satisfied giving their details out, they feel it is not safe for them. I think if casinos takes kyc very strict many gamblers may lost interest to gamble with casino which they wouldn't feel okay giving identification out. Gambling companies feels Gambling being private will be better for customers. The truth is that even if casinos begins kyc underage people will still look for a way to gamble. Kyc doesn't mean there won't be any way or any form of gamble for underage people to participate in gambling.
The only thing that can make casino and gambling companies to be strict on your young people is if the government can be involved in it then I believe for young people to get access in gambling will be difficult.
