nope , in youtube almost half of the videos has gambling site advertising ,a nd the famous 1xbet (in which questionable for being scammy) is spreading the social media and video sites luring players .
so if your children can access youtube that easy then expect them to be prone from this gambling advertisements.
best to limit their activities using gadget for sites that you will only allow them to use, better to get sites that even with pay but will keep them safer from this wild internet world .
Actually this problem can be solved with access to Youtube children. But actually it's true, some ads on youtube offer several gambling sites. I myself have children, for now I limit smartphone access. I educate him for other activities.
But behind that I also introduced him to the internet so that he has knowledge. At the age of children, they don't really understand it yet. They are more interested in games and social media.
