(Option to) Change Automated Post Deletion to Automated Post Archiving

[TomCasavant]

Pitch

Right now I've got my mastodon setup to delete posts older than a few months with zero likes, I think I'd prefer if they weren't deleted just set to private.

I'm not aware if ActivityPub generally supports switching privacy on a post after it's already been posted? My other idea would be tell every other server that the post has been deleted but just keep it private locally, that might be bad form though.

Motivation

Mostly so I can still browse my old posts if I want to rather than just being deleted for everyone.

an option to do something like this would be very nice

i don't think there would be another way to do it without sending a delete to other instances
if it's set to only viewable by yourself, as far as other instances are concerned, it's deleted.
