Advanced Strategy: The Subtle Art of Instigation; Keep Your Hands Clean by Having Others Do Your Dirty Work.
Its easy enough to just start ripping on someone. Its the advanced level of systemic trolling where the mischievousness is set aside and the diabolic is embraced.
Have a scapegoat or a monkey's paw. Understand your environment and the personalities involved and work to discover how various domino theories and chain reactions are applied. Its one thing to cause destruction and quiet another to come out of it smelling like roses. This tactic is often good counterstrategy against other trolls who are attention whores because they don't use it themselves nor are inclined to.
