I've been actively modding /r/DebateReligion (not exactly a topic which preempts drama) over on Reddit (not exactly a community which dislikes drama) for years, and at least from my experiences there I wouldn't dream of putting such questions to the community (especially with delicious "redacted" drama bait) before coming to some sort of consensus with my fellow moderators. You could of course argue (and I'd agree) that this is a more mature community.

Also, I wouldn't cite "presumption of innocence" when apparently unaware of much more pertinent principles (no retroactively applied punishments, not even hinting at a disclosure of legitimately presumed-private data). I do agree that a specific rule going forward would be a good idea, given how often this topic crops up. To establish such a rule -- via public discussion, if you so choose --, dangling (however unwittingly) the allure of a witch-hunt would have best been left out entirely.
