Once upon a time, "troll" meant someone trying to provoke a reaction for fun, from a type of fishing called "trolling", which involves dragging baited hooks through the water. Lately, as in this article, the term seems to be expanding into a general purpose insult for anyone whose posts annoy someone, sometimes only because they express a different opinion. Under the old definition, bad faith was a requirement. Having an honest argument or even being an honest jerk wasn't the same as being a troll. That seems to be changing.
