I do remember 2 "trolls" who were eventually outed, and one in particular was just cruel in how she was attempting to manipulate emotions.
I did report one to a moderator, and not that long ago (well, within the last 12 months). The post just felt not right, but it wasn't until I was trying to type out my report to the mods that it hit me: the story, if true, was emotionally devastating to the OP, and yet the whole post was too well-written: beautiful metaphors; neat paragraphs; no run-on sentences. I think most people have a tendency to write poorly when emotionally wrought.
There was one possibility that could have explained it: it was a true incident, but had happened years ago. If the OP had said, "Now this happened years ago," instead of, "This happened last night," I probably would have given a pass because years of processing the incident would have made it coherent.
But those trolls! They are despicable.
