@evan No... but maybe? I don't have a strong reason why they would. I feel like servers should only show their local content, for which they can control access based on publishing user's preferences.

There's also the question of caching: should you show cached remote content that has been deleted?

Except perhaps aggregators, and generally servers with nefarious intents that you can't control anyway (though you can block pushing content to them in the first place).

EDIT: ok, maybe in context of a conversation involving a local user.
