That makes a lot of sense, and it’s exactly the kind of mechanism I was hoping existed or could be added. Even if deletion can’t be instant across every server, having a federated “this content is deleted” response would give users real control instead of just hiding posts locally.

A system like the one you describe — where a delete request clears caches on other servers — would solve most of the privacy and user‑control concerns people have. It wouldn’t need to be perfect to be meaningful.

I appreciate the explanation. It’s good to know that this isn’t impossible, just something that needs coordination and implementation across the Fediverse.
