If this happens, `@someone@somewhere.else.example.org` (and their instance) should consider the interaction as having been approved / accepted. The instance can then feel free to distribute the interaction `Activity` to all of the recipients targed by `to`, `cc`, etc, with the additional property `approvedBy` ([see below](#approvedby)).
!!! Note
In the above example, actor `https://example.org/users/post_author` addresses the `Accept` activity not just to the interacting actor `https://somewhere.else.example.org/users/someone`, but to their followers collection as well (and, implicitly, to the public). This allows followers of `https://example.org/users/post_author` on other servers to also mark the interaction as accepted, and to show the interaction alongside the interacted-with post.
### Validating presence in a Followers / Following collection
If an `Actor` interacting with an `Object` (via `Like`, `inReplyTo`, or `Announce`) is permitted to do that interaction based on their presence in a `Followers` or `Following` collection in the `always` field of an interaction policy, then their server should *still* wait for an `Accept` to be received from the server of the target account, before distributing the interaction more widely with the `approvedBy` property set to the URI of the `Accept`.
