A forum "Troll" is a person who posts messages that more often than not are intended to create controversy or provoke an angry response, without adding anything constructive to the discussion. Trolls will often make use of insinuations or misdirected statements in order to pursue their objectives. A Troll's objectives are usually to cause controversy for the sake of causing controversy, undermine positive discussions, and discredit anyone with whom they disagree. They do this by creating an atmosphere of intimidation and ridicule. Since Trolls crave any kind of attention good or bad, one's best defense against a Troll is to ignore them, and let the forum leadership handle the Troll.
