@clacke Maybe we just need to make an Outbox feature. I considered server-side drafts, but drafts should be a client thing.

Here's my "outbox" feature idea:

The outbox is collected e.g., 60 seconds after you make a post. When you make the post it displays in your timeline feed just like you sent it. But it has metadata that would allow clients to show an icon that it hasn't actually federated yet. If you edit or delete it, the server changes it before it's actually federated. Everything I'm explaining could work without any clients needing to be aware the feature exists.

This alone would probably cut down on a significant amount of "delete" activities in the fediverse.
