I think by now it is pretty well known that content moderators working for platforms like Facebook suffer burnout, PTSD, and other mental illnesses due to their work[0]. This article is superficial but presents a look at similar workers in China, which I think is probably outside the consciousness of many HNers. It's interesting that the article only mentions overwork, not the mental toll of content moderation.
