Finally I have implemented a kind of trash in GoBlog. When I delete a post, it is first marked as deleted and can be restored within 7 days. Unfortunately the integration with ActivityPub is not that easy. ActivityPub allows to Undo a Delete activity, but Mastodon doesn’t support that, just like Mastodon doesn’t support Updates. 🙄
@en this sounds less funny now that I wrote it, apologies. :D
