What I meant with whistleblowing in terms of the fediverse is:

Whistleblower posts to instance A, and it gets mirrored on instance B.

Someone like Musk erases the post on instance A.

As the Fediverse currently works, the whistleblowing still exists on instance B, and cannot be deleted by an admin on instance A.

Asking a Musk to divulge who did the silencing is an exercise in futility.

That said, I’m totally on board with better tools to handle spam.
