I wonder how this works, though. I assume there is not any kind of automated system on the backend of HN trying to figure out what is "good content" and what isn't.
It goes nowhere. Someone with higher karma submits the exact same article with the exact same headline about two hours later, and it winds up on the front page of HN: https://news.ycombinator.com/item?id=10562207
(edit: Whoever downvoted this, I was responding to someone who goes by the name AdmiralAsshat, and I was obviously joking. But that might just be HN automatically downvoting people for using words like asshat. In which case, HN is being a pure asshat.)
