It should be available in other nostr clients, unless you mean allow people to use your list for their mute list?
Nostr (Damus) feature idea 💡
Export your muted users list to other Nostr clients

Wow! All I had to do was ask I guess lol. Just imported my keys to Plebstr and checked again, and you’re right. They’re all there. Tried it earlier this week and nothing was there. Had to start muting the same old bots over again. Thanks 🤝
Sharing a mute list would be dope though. I could share the file with friends so they can mute all the bots instantly when they first join Nostr.
Muting is not an effective way to stop bots, because bots can create a new account for each post. What would be better is a way to get onboarded into invite-only and paid relays.
