Those are all great points and I try to follow them myself when interacting online. I was actually looking for some kind of way to stop it from an algorithmic standpoint or some other fashion. Mainly because I don't like reading and wasting time on some minor nitpicks.
Not sure if I understood you correctly but as far as I know HN uses algorithms already for this sort of taks.
That's cool but I'd like to have better control, so I'm designing a custom HN curator myself. And I've noticed some other people have done the very same thing themselves.
