EDIT: The "flagging trustworthiness" could even help mods to find posts which might need to be unflagged quicker based on the average trustworthiness of the flags.
What's particularly insidious is that killed stories both don't show up in Algolia search results (this is somewhat understandable, but in the case of political flagging, problematic), and even where favourited (something I also do with some regularity), may not be visible to non-logged-in users and IIRC actually disappear from the index in time.
(I've also done that by mistake like four times.)
In a hilarious twist of fate, searching for that term brings up papers on either medical research or peer-review reliability problems in general[0]. You try to find data on a potentially abstract, complex societal issue, and come up with what can only be described as attention grabbing HN-catnip.
