You don't have to listen to the global feed to get an reply, and you can listen to it from free relays, where there is a lot of spam in the global feed. And to read the global feed, you can listen the global feed of paid relays.

That is, I do not understand why a reply will suddenly be missed (which was sent, for example, to a free relay, where there is a lot of spam)? A free relay is enough for him. In addition, the relays relay each other's network events. Also, if you write a message, your client sends it to both paid and free relay. It seems to me that there should be no problems.
