so like, you know a relay can profile you super easily just with client fingerprinting right?  being annoyed with auth, i hope its for good reason and that youre aware that clients already send telltail signs of what pubkey you are just from making reqs every time they open.

if you already know this and have your own client or etc, or do not feel this fingerprinting is as annoying as auth .. you can use a shared auth key with multiple people, and have the same level of obfuscation for your reqs that you would without auth.

the benefits of auth are many on the operation side (dynamic req limiting) and client side (DMs etc).  so i think its very important to head this direction.. whether its pubkeys, zaps, ecash, or zkps i dont know?  nostr does not have the equivalent of a robots.txt
