> Trolling can refer to a variety of online behaviour. In some circumstances, the intent of the trolling behaviour may even be to amuse and entertain. However, in my research, I have explored trolling as a malevolent behaviour, where the troll wants to hurt their online victim.
You can argue that "troll" isn't the right term, but then what is the right term for this? I think it's reasonable to use and adapt the term for this purpose, for lack of another more specific term. The article is describing a subset of trolls.
