That searches all relays?
Discussion
Most if not all of them, yes.
Profiles are easy to download.
Interesting.
I find this mildly hard to believe.
How would any client even know about all the relays that exist? And reach out to all of them all with a search query.
Relay urls are placed as hints on Nostr events. A client can just collect them all. Every if you are using a hidden relay, something always leaks.
