With residents, in Second Life, whose intentions are good, there are those, whose reasons that are quite malevolent. "Griefers", in general, are those who execute actions in Second Life for evil and mean purposes; to cause entropy to regions, residents and/or his or her environment.

Griefers will do anything to make others unhappy, even if it means losing one's Second Life account, or even getting involved with governmental authorities. In some cases, griefers will go to extents in creating a DOS attack upon the Main Grid, forcing the entire game to shut down, and refresh, due to an incapable amount of calculations and processes within the asset and space servers.
