Even the word troll refers to an old made up creature that lurked under bridges and were death for any that tried to cross their bridge. I believe, for something or someone to be trolling there has to be malicious intent. Seriously, when is the last time you saw someone praising a troll for lifting the mood of a discussion without insulting one of the parties?
I think you will morph the term trolling to the extent that all conversation is considered trolling. Right now Bas' definition could be applied to just about any situation.
