Just not only gambling platforms kids are also get addicted in porn sites which is quite common now. Due to that reason some countries government block porn sites on their region but no one can say that its gonna work completely. In modern world kids have knowledge about VPN and they can easily avoid all restrictions by that. In a situation like this parents have to play the key rule to keep their kids far from this kinda things. Actually anyone can get register on a casino site where authority can only get information about users age during KYC submission. In some cases kids use their parents documents to pass the KYC process and its really unstoppable IMO. So IMO its necessary to keep an eye on kids internet browsing which may be a better solution in this kind of circumstances.
