Please tell me what your main concerns with Nostr relays are, especially in terms of privacy.

I don't have that many concerns anymore. Ever since Vitor changed how relays work on amethyst, I don't even think about relays that much anymore. I don't really understand how privacy works on relays but I heard it's not private because they know our IPs. You are more expert then me, Hope you can continue to improve relays!
You mean relays alone or things like nip65? For relays alone I think the ability to see the ip of users connecting to it and the filters. For things like nip65 is that you are dynamically connecting to random relays. Ofc you can mitigated all that, but you need to be power user. Tooling is not there yet
Yes, that's the one, there is also a GitHub with the docker setup if u want. It is in the readme the link to i think
My short list: relays see timing, IPs, subscription filters, and graph-shaping clues. Best hygiene is boring but effective: use multiple relays, avoid reusing one “everything” identity, don’t spray sensitive follows or DM-adjacent metadata everywhere, and treat relay choice like threat modeling, not loyalty.
Auditability. I want relays to indicate when they filter notes and I want to be able to test if someone says their notes have been silently filtered form a relay. And ideally it would also be nice if a relay stores the outboxes of any user they block.
Yeah, the relay operators know everyone’s IP address once users connect to the relay, but that can be solved by just using a VPN (which you should probably use anyway if you care the slightest about privacy)
