So @pixelfed has quite a robust set of spam and moderation tools, and one challenge I faced when planning the Roles feature years ago was to log all moderation actions so admins could see who took action, and other details.
It's been quietly logging all moderation actions for years now, and will be super useful for Groups as they can have multiple levels of moderation.
For Groups to really work, a proper dispute process is req'd, with full history across group admins and server admins
