probably just a random one shot but i just spotted someone at the ip address 121.99.222.6 nostr:npub17ru9ehv7k5qe9s9yh3nv2trf62a7phyvfxldtq5ly0k6up0rq75sme6g0n is returning auth challenge responses with the challenge missing

i've seen this before, just on the off chance it's actually someone who is developing stuff and that's not a one-shot signer that has been incorrectly implemented, the auth is not populating the challenge field correctly
