You, too, could become a troll. Not a mythological creature that hides under bridges, but one of those annoying people who post disruptive messages in internet discussion groups – “trolling” for attention—and off-topic posters who throw out racist, sexist or politically controversial rants. The term has come to be applied to posters who use offensive language, harass other posters and generally conjure up the image of an ugly, deformed beast.
