A troll in Internetspeak refers to an entity which involves itself in discussions purely for the purpose of disturbing other users and making itself feel important. A troll usually has little or no interest in contributing to the development of the site in question and is interested in : * Deliberately angering people. * Breaking the normal flow of debate/discussion. * Making itself the main topic of interest or discussion. Most importantly, trolls take away from productive work. The only ethical way to avoid this is to stop feeding the troll and go about your usual work.
