And you don't even have to throw the nuts *at* the podcaster. If they're pubkey locked anyway you can just toss them anywhere. Eventually they'll get to the host. Either because their wallet crawls the web or their friend finds it on nostr and forwards it.

You could add a "has this been claimed yet" API call to mints so when software encounters a nut somewhere they can decide to either ignore or kick it down the road somewhere.
