An internet 'troll' is an abusive and obnoxious user who promotes hate and disharmony in online communities. Named after the wicked troll creatures of children's tales, an internet troll is someone who stirs up drama and abuses their online anonymity by purposely sowing hatred, bigotry, racism, mysogyny, or just simple bickering between others. Trolls like a big audience, so they frequent blog sites, news sites, discussion forums, and game chat. Trolls thrive in any environment where they are allowed to make public comments.
