You sure seem to have an axe to grind with this site in particular, when in reality it is not wholly better or worse than any other social media / discussion platform. In fact, in some ways it's somewhat innovative with some really simple ideas that help distinguish it from the rest.
I don't know why you think moderators should work for free. That's up to the platform to decide.
Also, I'd take the lenience found on HN any day over the ban hammer / shadow ban / user siloing approaches that others sites cave to. As we've seen, there is no perfect approach.
