To which point do you refer? For my first mentioned one we have got a special document at [code].well-known/x-social-relay[/code] that every Friendica server publishes that contains information about the subscribed hash tags.

And concerning the second point, I imagine some relay service that does not simply forward everything, but that knows which content you you are interested in. So when you subscribed to user A and user B posted something in a thread that user A started, then the relay would forward it to you, although you never subscribed to B. And when then the account B got deleted or blocked, then of course you would be notified as well.
