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.
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.
