@pfefferle @julian@activitypub.space FWIW, the way I handle this in @encyclia is to edit the post content to something to the effect of “This content is no longer available” instead of actually deleting the object. Mastodon (and other) servers may let people see what used to be there if they dig into the version history, but for the type of content Encyclia touches, this is generally not much of a problem.
But if you want to push for better `Undo(Delete)` support in the ecosystem, you have my axe! 🪓
