In YouTube, there's a notification or warning if a video is not suitable for young people like below the legal age. I think it's the parent's responsibility to always watch their children's activities online.
Yes, it is. But the young people can skip or continue watching the video without their parents or adult people around them knowing. It is hard to control young people to avoid that thing as they can watch it alone in their rooms and not tell anyone except their friends.
That can attract them to follow the bets from those videos without knowing that they are fake. We already see many young people's getting deeper into gambling games and the sad part is their parents does not know their activity and only know after they have a heavy gambling addiction.
Not only for kids, even adults are sometimes get enticed by the influencers, but this is the reality, it's the life of a gambler, you either follow, fade or make your own analysis. There's a risk but if you keep making mistakes and you did not adjust, that means you should not gamble as it's not for you.
