HackerNews is a limited-focus link aggregation and comment platform. It doesn't require the kind of moderation that larger scale, broad-focus social media platforms do.

I don't envy the work that Dan and Scott have to do in the slightest, but I don't think they'll end up with PTSD from it. At least, that's what I gathered when I read "The Lonely Work of Moderating Hacker News"[0], especially this description of it: "Pressed to describe Hacker News, they do so by means of extravagant, sometimes tender metaphors: the site is a “social ecosystem,” a “hall of mirrors,” a “public park or garden,” a “fractal tree."
