Earlier quoted context omitted.
"Although you don't see those threads, search engines do. HN uniquely has a high page rank and low moderation, making it a prime target for bad actors to poison search results with abuse, bigotry, and nastiness. This isn't low-level trolling, but an organized attempt to destroy lives, including of developers in our communities."
Always funny to me to read something like that. HN has high moderation, one of the highest I've seen on modern fora, only a few steps below r/AskHistorians for example. I don't see this "abuse, bigotry, and nastiness" here and even if there are comments like that, they are quickly downvoted and dead.
There were a number of remarks on the prior thread by people making conspiracy claims, harassment, insults etc. Some of them get flag-killed, some just down voted but ultimately the users on the site still remain.
Of course I'm not one to be above such a thing in terms of insulting people occasionally but HN is really quite permissive in terms of what you can post and get away with. It takes consistent and repeated bad behavior to get a warning, and even more to get banned. And if you're an expert in being politely venomous you can get away with even more. That's why the outside perception of HN tends to be a lot worse than the inward one.
