The Patriotic Nigras (AKA the PN) are a highly prominent griefing group in Second Life's main grid. Despite waning membership (estimates put their current active members at around 20, from approximately 50 in 2008), the group continues to maintain a public wiki that lesser-organized griefers can utilise to cause damage. The PN are responsible for a wide range of attacks, ranging from simple trolling to broad-scale denial of service attacks on the simulators and grid infrastructure.
