Someone posts Paul Graham's post talking about "woke" ideology and mods/admins do nothing about it
While this one stays flagged
At least be consistent
Most of the users that can [flag] also have the option to [vouch]. If enough vouch the flag is reveresed (as far as I know).
Addendum1: I haven't compiled a detailed cross referenced list of observations about HN .. but it's got a lot of little subtle quirks from custom coding .. I suspect there's a window for submission vouching that's only open to users with certain other privlege escalations, or perhaps a stochastic element throws that chance to a random few .. eg: I have no option to vouch for this flagged submission, but I have had that option on others.
Addendum2: Jtsummers may well be right. There may also still be other odd little factors <shrug>.
