In October, Old School RuneScape players discovered a game-breaking exploit for a 16-year-old minigame. Developer Jagex was surprisingly cool with the whole thing - in fact, now the studio has dedicated two themed worlds in the exploit's honor.
You can read more about how OSRS fans broke the game to farm XP and get addicted to fruit at that link, but in short, there's an ancient stealth minigame in the MMO where you have to sneak past guards to steal some juicy fruits called sq'irks. Players found that, by rushing the minigame in sufficient numbers, the guard AI would break, protecting most of those participating from being discovered and failing the minigame. This proved to be a pretty lucrative way to farm Thieving XP, and the whole community soon became obsessed with, uh, "sq'irkin'."
