I think in this digital era it is very difficult to control the activities of teenagers, because just by having a smart phone and having an internet network, they can do whatever they want. Because anyway, even though the government banned gambling, the reality is that many influencers promote gambling themselves. Sure, many influencers have been arrested for promoting gambling, but the reality is that gambling itself has been publicized so underage children will still be able to access it. So yes, any rules to limit the age of gambling, I think it is never effective, because the reality is that the gambling industry itself also continues to increase.
Age restrictions work relatively well when it comes to physical casinos, since they have personal on the ground checking people out and if a person that looks to young to be on their establishment appears they will immediately ask for an identification, but online this is very different, we know that most casinos do not ask for anything related to your identity until you attempt to make a withdrawal, so a teenager can gamble and lose everything and no online casino will do anything to stop him.
It needs to educate the influencers so they will not promote gambling to public and there are a strict rule for them about promoting something. If the government can cooperate with the influencer and gives education to their citizens about the risks of playing gambling, maybe that can works and the citizens will not trying to playing gambling.
And for physical casino, they must strictly limit people and will not allow teenager to enter to the casino although that can not be apply to the online casino but the online casino can use the other methods to prevents teenager to playing gambling.
Casinos is a very risky and addictive game, and it is more harmful for Adolescents. Adolescents should be kept away from this game as much as possible, because what they do in their youth, that's affect effect their beautiful life in the future. If they become addicted to gambling at a young age, they will become an full addicted gambler. And they will never be able to grow out of this dangerous place, and their lives will slowly move towards disaster, and their beautiful future will be ruined.
It is necessary to strictly control the access of teenagers to physical casinos, and nowadays every physical casino controls this well, so that teenagers cannot go to physical casinos in any way. But they enter online casinos and start gambling. Hence the age verification system should also be tightened in online casinos, so that they cannot gamble with fake information. And the parents of all these teenagers should teach them properly, and keep an eye on them, so that they don't gamble secretly. And if awareness education programs are introduced everywhere, the younger generation will get an early idea about gambling/casinos and its harmful effects, As a result, they will learn about the harmful effects of casinos and stay away from casinos.
