It's hard to prevent something that is beyond our control, such as some of the points you mentioned in this thread. I look more at how the human resources themselves are, also how someone does not involve a small child to buy tickets to a gambling shop, even if only asked by their parents or whatever. There's not much you can do, especially like the points of advertisements on television or the like. Well, this phenomenon depends on how you behave, then prevent it for you and your closest family. How do you provide knowledge and understanding related to gambling, provide an understanding of what is allowed and not at his age, until a child reaches adulthood in responding to something. It doesn't mean that I'm skeptical of phenomena like the ones you share in this thread, it's just that the best steps we can take are applied to those closest to us. The problem is, we can't prevent something beyond our control, let alone influencing many people. At least what we can do is, starting from ourselves and our families. Provide an understanding of what gambling is, and when it is permissible to be involved in this type of entertainment.
