I was discussing this review as it fits in a larger context. I usually think of a troll as someone who posts a comment completely off-topic, or stuff like "stfu u r a looser poopyhead."
One could make an argument that posting a reply to a comment thread that only insults the original commenter (um, calling them a troll and autistic?) would also be a sufficient qualifier of trollism.
God forbid someone having a contrary opinion.
