Old School Runescape went offline for several hours earlier today, after players discovered an issue that let them crash the game via a 14-year-old tradition.
Earlier today, OSRS got an update with some relatively small technical changes. Shortly after the update went live, players began to realize that sending rainbow text through the in-game chat would crash the game - not just for themselves, but for anybody in range to see that text. That's something that could pretty easily be exploited by unscrupulous players looking to get others killed.
