Perverte Justice Foundation, Inc., more commonly known as Perverted-Justice (also known as PeeJ), is a California-based non-profit organization that investigates, identifies, and publicizes adults who solicit online sexual conversations with adults posing as children. Perverted-Justice's methods are controversial, and a number of critics have labeled these actions harassment. Perverted-Justice consists of volunteers who carry out sting operations by posing as 10-15 year old minors on chat sites and waiting for adults to approach them. After obtaining identifying information from these men, who may offer their telephone numbers and other details so that meetings can be arranged, the organization passes the information on to law-enforcement. Perverted-Justice has attracted media attention, both laudatory and critical, as a result of their collaboration with Dateline NBC on a series of televised sting operations called "To Catch a Predator".
