I now understand the meaning of a "forum troll".
From Urban Dictionary:
From Urban Dictionary:
One who intentionally posts on an internet forum to gain attention rather than contribute actual content. Some trolls may appear to contribute and may actually have meaningful posts, but the posts will be made in such a way that content is overlooked by design.
Trolls are people who want to get on your nerves. They will usually lurk around the forums and wait for an opportunity to annoy or attack a user. The best way to ignore a troll is not to flame back, but to report and move on. Trolls are no good and should be exiled.
