Seriously crazy stuff going on with PSN account resellers in this article from Patrick Klepek:
A few weeks ago, Mic Fok got a weird email. The person writing it claimed they’d been playing Overwatch on a PlayStation Network account for more than six months, but the password had changed recently. But why would Fok know anything about this random dude’s account? As it turns out, they’d “purchased” Fok’s account through a website called PSN Games, one of many businesses trafficking in the selling of cheap games by sketchy means.
The individual who bought Fok’s account was an Overwatch fan named Bennett Eglinton.
“Hello I purchased overwatch from psngames.org and this email was used as the account info,” reads an email from Eglinton, sent in early March. “However the password I was given for the PlayStation Network sign in no longer works. Did you happen to change it? Can I get the new info.”
As Patrick mentions in the article, this is a great reason to use unique passwords everywhere with a password manager. I use and recommend 1Password despite them switching from standalone purchases to a subscription. You should also use the free Have I been pwned? service to check all of your email addresses for public account credential leaks.
