I read this comment written by Meta Andrew T.:
"I thought moderation policies were supposed to be public." just want to mention that mods also have their own mod-only help pages which have a header mentioning "This information is intended for moderators only; please don't share the specifics in public", so while some of the moderation policies were posted on Meta publically by staff, not all moderation policies are public. (Though in the case of AI policy, the problem is really with the discrepancy)
Why aren't all moderation policies made public?
