[Standards] Unmoderation/soft moderation

Hi folks, I'm curious if anyone has thoughts on being able to undo a XEP-0425 moderation action. The use cases I have in mind are: - admin accidentally moderated the wrong message - one admin moderates a message, but after consideration/discussion with other admins, it is decided it shouldn't have been moderated - reverting automated moderation after human review This last point is the one that sparked this email, however I have experienced the other cases as well over the past couple of years. For the automated case, all I necessarily want is for clients to hide (by default) messages in a group chat which are likely to be spam, for example if some trusted but non-admin users have reported it. When an admin does respond, they could then moderate the message fully, or unhide it (if the report was incorrect, e.g. malicious). This hiding/unhiding could be a new XEP, or we could solve "unmoderation", which solves the other use cases and probably makes the most sense. Thoughts? Regards, Matthew
