Yes I see a lot of people streaming online not only the children will be exposed to gambling but of course out of their curiosity they will would definitely try this out especially they are about to win real money, I think youtube and twitch are not that strict in regards with this kind of contents.
As strict as restrictions are on the Internet, they are easily circumvented, and we all know that very well. As I have already repeatedly said it makes absolutely no sense to forbid something to a child, but to teach him to fully trust you and listen to your advice and recommendations is quite possible. Once you get your child's trust you can easily find out what he does on the Internet and at the right moment you can convince him to give up this or that content or hobby.
we have a different way of disciplining our kids, me, I would never expose them to online gambling as I know if they learn, I might not be able to monitor them and since they are just kids, they are not matured enough, so they might easily get addicted, and I don't want to blame myself for being an irresponsible parent too.
