I could be completely wrong here, but is it possible the Chinese government would use a tactic like this to get the IPs coming out of China blocked in order to block Nostr usage to the average citizen? The fact that it's coming directly from the mainland makes me wonder.

Since they can't firewall Nostr, get the Nostr interfaces to block them instead? I realize they could also go to the relay directories and find and block that way too, but this just seems to fill gaps?

If they don't want people talking on Nostr in the first place, they don't care if they get blocked, right? 🤔
