I wouldn't go as far as to say it was deserved. There's easier ways to teach lessons. Guy was a troll. That said I can't have much sympathy. As a parent, my child has to know you don't try to cheat, nor do you trust a stranger on the internet. If this happened to my kid where she gave a stranger access to her PS4, I would be restricting online access for a while. Possibly a few years.
