Why do you think HN does not expose flaggings data?
( You'll need Showdead: ON in user options to see most of those comments, they're flagged, dead, and spamming a dodgy cryto scheme )
Or drop flagging as a feature completely. Looks easier :)
Treating HN this way is a misunderstanding of its goals and would make HN much worse. 'nerd messageboard with less yelly conversation' is about as good as one can hope for the actual aspirational goal of 'place for curious conversation'.
