Unfortunately-named news site Gamepron is reporting that Mr Garry Newman, creator of Garry’s Mod, has gone and done something clever: he introduced an error to his game, an error which only affects pirates. It was a trap! Said pirates even turned up on the G-Mod forums to discuss why their game didn’t work. Reporting the error even revealed their Steam id. Hilarity ensued.
More of this sort of thing, Internet. (Even if it is basically pretty sinister.)
