Oh nice. How does it prevent actual spammers from writing to it? Or does it not matter because the spam notes are never shown to anyone (so it’s maybe an issue for storage/ddos but not the nostrich’s UX)? 

 It doesn't actively do this. If you follow a spammer then a spammer can write to my relay. It's up to the community to not follow them. But I can always blackliat an npub. 

 Cool, that’s an interesting approach. I’d imagine it works best in a “lots of smaller decentralized relays” sort of setup, right?

Also, added 🤙
