If you get a lot of spam replies, I recommend using a popular paid relay like nostr.wine. You don't have to pay to use it as a public inbox relay, since you'll only be reading from it, but only those who have paid will be able to write to it. Another option is a web-of-trust relay or two, and the reply spammers likely won't be on the relay's white-list. A more extreme option would be to run your own zapbox relay, which means you won't get replies from anyone except those who have zapped you above the threshold. It's sort of a dynamic paid relay that resets its whitelist on a recurring basis.

If you don't have a lot of reply spam, public relays work just fine, and broaden who is able to reach you when they reply.
