As a parent to the child, can you allow the child to use your details to pass KYC verification, if asked? And if you do that, does it also mean that you are supporting underage gambling?
As a parent, of child should ask to use my details to pass KYC verification for a casino, then I would consider myself to have failed not just in my role but also as a father. As long as you live under my roof gambling is banned. It is not even debatable.
