Yeah I don’t think it does, and like I say you would only be able to see subscribers in your local instance. Seeing subscribers from other instances would rely on that other instance actually sharing that information - while lemmy could be written to do this, there’s never any guarantee that another instance is using pure lemmy code and not some modified version.

I don’t think reddit ever had that capability either. Not for mods anyway, I’m sure admin could see that stuff.

In any case it would be very easy for bots to circumvent your monitoring - they simply would not subscribe, and instead just browse the community directly.
