In 2006, RuneScape released a Construction skill that added player-owned houses and accidentally enabled one of the most famous PvP exploits in MMO history: the Fallador Massacre, which saw unlucky merchants killed in safe zones for their valuables after players worked out a way to obtain glitched PvP status.
On November 19, 2025, Old School RuneScape released a Sailing skill that added player-owned boats and accidentally enabled piracy, which is nowhere near as bad as the massacre, but the game's new fleet of pirates is carrying the PvP flame in their hearts.
