Although *maybe* the outbox makes sense (only actors perform activities), the claim that actors are the only AS2 type allowed to have an inbox is not consistent with the Linked Data Notifications (LDN) origin of the AP inbox. LDN allows any entity to have an inbox. Unfortunately, this breaks some actor duck typing techniques. #ActivityPub

@silverpill An duck rule like the following would fail...

❌ if an object has an inbox or outbox, then it is an ActivityPub actor.

for objects that aren't actors but have valid LDN inboxes (the same property as AP actor inboxes).
