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.
Example of such trolls are Wintersfire, Vent etc.. If you come across these, but ignore and move on.
If you're new to Basil, wintersfire shouldn't be a problem. Vent is the real troll.
