Yes, what I meant is, now existing users can more easily find new ones and talk/guide them about Nostr directly.

I have no experience with Japanese users bot (obviously 😅).

What exactly does it do? I know only 1 thing:

The bot follows new Japanese users, but follows don't have notifications - so the new users may not even notice the follow. But if they do & check the follows of the bot, they can find all Japanese Nostr users in one go
