I think I wooshed some people with this comment. Gonzo journalism is when the journalist participates in the story. Gonzo research then is when the researcher participates in what they're studying. In this case, the researchers ostensibly researching toxicity are doxing people, which is toxic behavior. This makes them gonzo researchers.
That's a logical fallacy. Breathing must be toxic because dirtbags breathe.
AIUI, doxxing requires either publishing a subject's days or taking action against the subject. The authors of this paper day they have no intention of doing so. It's mild.
