It makes me want to talk about how the concept of the troll has evolved from something specific to something very general. I glanced through the article and none of the behaviors it listed are what I'd consider troll behaviors. They're just the patterns of mild mental illness.
Trolls, in my old-man's definition, are almost a type of hunter, looking to bait and confuse their victims.
Trolls wouldn't be the hoards suffering from "sanctimony, emotional aridity and ideological orthodoxy", and exhibiting BPD/DID behaviors. Trolls would be the people trying to provoke the above.
