From the urban dictionary: http://www.urbandictionary.com/define.php?term=troll
One who posts a deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument.
You see, I occassionally get accused of spruiking property since I am a Buyers Agent who stands to profit from advising people to purchase property if they signed up to our services.
Trolls like to point this out ad nauseum. But I would have thought it pretty self-evident if you read my signature. In any event it is funny because I advised you NOT to buy any more property for the time being.
