There are a few issues with the decision here
- Is the amount of money won life-changing?
- Is the casino suspicious at all about the account?
- What are the laws in said country about gambling, identity deception, and more importantly, contributing to the delinquency of a minor by a parent

The thing is that if your kid has used the email gokusayanwarrior@ something and that email is linked to some stupid post on social media, the casino might have double thoughts about it, not even mentioning emails discussion, attitude in rooms and so on....
So if you live in a 3rd world country with no laws, year, why not risk it? if you live in the US or EU, I don't think it's worth the risks!
