I guess most of us are "trolls", then, if we're going to hold to the strictest definition of the term:
"As described by Robert Bond in The International Review of Law, Computers & Technology, trolls usually exhibit a typical pattern of behavior:
In ‘The Art of Trolling’ published on the web it is suggested that ‘in Usenet usage, a “troll” is not a grumpy monster that lives beneath a bridge accosting passers by, but rather a provocative posting to a news group intended to produce a large volume of frivolous responses. The content of a “troll” posting generally falls into several areas. It may consist of an apparently foolish contradiction or common knowledge, a deliberately offensive insult to the readers of the news group or a broad request for trivial follow-up postings.[3]
In general, then, trolls actively seek confrontations whenever they post, for their own enjoyment and that of lurkers who read their posts. Typically, the best trolls only reveal their true intentions to lurkers observing the troll’s activities."
