There are loads of kids out there who try and ask publishers for free games. Most of them are at least up-front about their pan-handling, maybe pointing to a YouTube or Twitch channel that nobody watches. But then there's this guy, who was busted trying to straight-up scam indie publisher Devolver.

I hope he actually tried to enter those codes a few times before realising.
Note that the email address "[email protected]" isn't even Devolver's actual email, which you can find by visiting the company's site; it's a very old email address you'd only find in a Google search (or at the bottom of old fake press releases).
