The actual figure may not be 20% but generally in some areas more than 15%. TerminologyAn internet troll is someone who intentionally posts messages about sensitive topics constructed to cause controversy in an online community such as an online discussion forum or USENET groups in order to bait users into responding.[1] They may also plant images and data on networks that others may find disturbing in order to cause confrontation.
More specifically a troll is an insult or accusation made against a poster. It would be highly unusual for any internet poster to claim the title of troll, rather a community member may try to deflate a post that is controversial or thought provoking by referring to it as a “troll”. In usage troll is more of an insult like:
lame
stupid
idiot
f**king
b***h
pathetic
useless
brainless
go and die
something hates you
childish
such a -insulting word- -noun-
suck, sucker
dumbTo call someone a troll is to say that any dispute over a post is not valid not because the issues raised are not valid, but to claim the intent of the poster invalidates the post. As a speech act the term troll is generally used as an ad hominem argument, attacking the poster rather than the content or issues of the post.
Intent/ MotiveAttributing intent to trolls is a very difficult issue since by its very nature to call someone a troll is to already assume an intent, that they are posting only to cause problems. So once a person is called a troll they have already be categorised by the speaker as someone with a certain intention.
Many people call others trolls, few call themselves trolls, so a troll is not a self constructed identity but rather is a category constructed via the speech act of calling someone a troll. Perhaps the more interesting question is what motivates speakers to label some as a troll.
Trolls can be existing members of a community that rarely post and often contribute no useful information to the thread, but instead make argumentative posts in an attempt to discredit another person, concentrating almost exclusively on facts irrelevant to the point of the conversation, with the intent of provoking a reaction from others. The key element under attack by a troll is known only to the troll.
A person who retaliates (using whatever means) as a result of a misunderstanding (or as a way of rebelling against the overzealous application of rules) is not a troll.[5] A troll is a person who approaches a board with the specific intention of stirring things up, either as a goal in and of itself or as a means of attacking the board perhaps motivated by opposition to the ethos of the board. For example, a neo-Nazi approaching a Jewish forum with the intention of attacking the members, purely because the neo-Nazi knows the forum to contain Jewish members, will be considered a troll.
The general element, that determines whether a malicious user is a troll or not, is the level of indignant emotions present in the person, coupled with the person's history with the forum or group. An indignant user who has had a previous normal relationship with the group is not a troll, even if the user uses methods of attack that are characteristic of a troll attack.
A troll's main goal is usually to arouse anger and frustration among the message board's other participants, and will write whatever it takes to achieve this end. One popular trolling strategy is the practice of Winning by Losing. While the victim is trying to put forward solid and convincing facts to prove his position, the troll's only goal is to infuriate its prey. The troll takes (what it knows to be) a badly flawed, wholly illogical argument, and then vigorously defends it while mocking and insulting its prey. The troll looks like a complete fool, but this is all part of the plan. The victim becomes noticeably angry by trying to repeatedly explain the flaws of the troll's argument. Provoking this anger was the troll's one and only goal from the very beginning.
