Internet troll - Wikipedia, the free encyclopedia
This remind you of some version of some forum we once knew?
Internet troll - Wikipedia, the free encyclopedia: "Vicious cycles
Many times a person will post a sincere message that they are emotionally sensitive about. Skillful trolls know that the easiest way to upset them is to falsely claim that the person is a troll. On other occasions a person may not instantly understand or fit into the social norms of a forum where most people are the same - and so acting just slightly out of social norms, often unintentionally, for legitimate reasons gets the poster called a troll. Whether they actually 'are' a troll depends wholly on whether one takes the political view of trolling, in which motives are not considered."
