i think the relay it mentions in the message is the one the note *goes to*
at least, in this case: i see it coming from primal.net in my client, and it mentions primal.net

what i wonder is where it reads the original note from, because i don't write to primal.net
i suspect damus.io or nos.lol even though they don't have the spam themselves 😀  

 Yeah, it's probably like this:
1. Bot subscribes to kind 1 events from a big set of relays
2. Bot receives a new event from any relay
3. For each relay it wants to write to, it signs a reply event (mentioning the relay url).
4. Send all the signed reply events to all relays
