Wikipedia über Internet Trolls

In der Wikipedia steht eine nette Beschreibung über Internet trolls.

On the Internet, a troll is a person who posts messages that create controversy or an angry response without adding content to the discussion, often intentionally. Though technically different from flaming, which is an unmistakable direct personal attack, trolls often resort to innuendo or misdirection in the pursuit of their objective, which is to create controversy for its own sake, discredit those with whom they disagree, or sabotage discussion by creating an intimidating atmosphere.
