I would ask nostr:npub1f6ugxyxkknket3kkdgu4k0fu74vmshawermkj8d06sz6jts9t4kslazcka . What alternative do you recommend for email?

I'd also recommend just giving protonmail a recovery email that doesn't link to you and always use it with a vpn. That's really the only two weak points that I see that can link to you.
