The following information was taken from Wikipedia. It has been edited to help identify this particular Troll.
In Internet slang, a troll is someone who posts inflammatory, extraneous, false or off-topic messages in an online community, such as an online discussion forum, chat room, or blog, with the primary intent of provoking readers into an emotional response. The noun troll may refer to the provocative message itself, as in: "That was an excellent troll you posted". While the word troll and its associated verb trolling are associated with Internet discourse, media attention in recent years has made such labels subjective, with trolling describing intentionally provocative actions outside of an online context. For example, mass media uses troll to describe "a person who defaces Internet tribute sites with the aim of causing grief to others."
The verb troll originates from Old French troller, a hunting term. The noun troll comes from the Old Norse word for a mythological monster.
In modern English usage, the verb troll is a fishing technique of slowly dragging a lure or baited hook from a moving boat.
The word evokes the trolls of Scandinavian folklore and children's tales, where they are often creatures bent on mischief and wickedness.
In Japanese, tsuri (つり) means "fishing" and refers to intentionally misleading posts whose only purpose is to get the readers to react, i.e. get trolled. arashi (あらし)
In Korean, nak-si (낚시) means "fishing", and is used to refer to Internet trolling attempts, as well as purposefully misleading post titles. A person who recognizes the troll after having responded (or, in case of a post title nak-si, having read the actual post) would often refer to himself as a caught fish.
Concern troll
The concern troll posts in Web forums devoted to its declared point of view and attempts to sway the group's actions or opinions while claiming to share their goals, but with professed "concerns". The goal is to sow fear, uncertainty and doubt within the group.
Application of the term troll is subjective. Some readers may characterize a post as trolling, while others may regard the same post as a legitimate contribution to the discussion, even if controversial. Like any pejorative term, it can be used as an ad hominem attack, suggesting a negative motivation.
Regardless of the circumstances, controversial posts may attract a particularly strong response from those unfamiliar with the robust dialogue found in some online, rather than physical, communities. Experienced participants in online forums know that the most effective way to discourage a troll is usually to ignore it, because responding tends to encourage trolls to continue disruptive posts — hence the often-seen warning:
"Please do not feed the trolls"
