Yes seriously. Considering the large proportion of people living paycheck to paycheck 50k in sudden debt doesn't ruin lives it ruins families. If his parents aren't rich as fuck you're talking about losing homes outright. PayPal should definitely refund. If not the parents need to due out something.
There are consequences to your action. He had a paypal account and donated money and he got burned doing so
This is not a "my 3 yo kid clicked on buy gems in a mobile game" situation
