Proper trolling isn’t winding people up for fun, or bullying, or posting deliberate offensive, derogatory or defamatory material. Its starting or contributing to a conversation in a way that prompts a knee-jerk from people to reveal more about themselves than they are aware of, and especially to make them reveal their flaws. Socratic Irony.
Most PR driven news stories are trolls, most radio/TV phone-in-phone-in-your-opinions shows are trolls. The Daily Mail is a massive troll site, trolling both its readers and its non-readers
It has been suggested that the perfect troll is a thread that starts:
“I see Margaret Thatcher has been rushed into hospital. Heres hoping!”
