I can't speak for anyone else, but in my experience what is usually referred to as a troll is someone who comes to a board like this to just make fun of people or post just to get a reaction and a laugh just for kicks, but have no other reason for being here.

That has nothing to do with how much someone posts, or the quality of the posts, as far as I understand it.

I never got the idea the original post was meant for as a message for anyone in particular when I read it.
