#Mastodon and other #fediverse instances should have a feature to recover deleted posts from another instance's reply to that post. If my posts are cached on another instance, I could forward them to this instance via a DM or regular reply. If you have to rollback a snapshot on your instance, at least another instance will have those posts saved, and you can forward them if you want to see them again.
Starnix is a community effort lead by FOSS enthusiasts for the purpose of establishing ActivityPub Software and promoting Fediverse usage. The primary topics for this Mastodon instance include but are not limited to software technology, including FOSS, Unix and Unix-like operating systems, and gaming.
