I can't believe that. Nothing will be perfect but there must be some combination of options that can improve things significantly.

Maybe it is volunteer mods. Or HN require new members to pass a 'best use' rules questionnaire before posting (or exiting offenders). Or they run algorithms to find users that vote inline with the spirit of HN and ninja ban people they downvote.

I dont profess to know the answer but there must be improving options available. And further someone solving this is a quite important concept (and potentially a great business too), as while here I want a better conversation, the recent US elections showed us what bot armies and paid shills can do, there are probably options that can be employed in the wider internet encourage genuine conversation in general.
