So I just ran into this problem and I was wondering if anyone knew the lemmy software well enough to answer this. I’m seeing different stats on communities depending on which instance I view it from, and I don’t know what the true statistics are.

Using a community I moderate ( /c/[email protected] ) as an example:

If i view the sidebar from this link: https://lemmy.world/c/maliciouscompliance

It says 91 users / day, 143 users / week, 2.19K subscribers

But if I view it from this link: https://lemmy.ml/c/[email protected]

It says 42 users / day, 85 users / week, 45 subscribers.

I’m assuming the user count is based on that specific instance, and subscriber count when viewing from another instance is based on subscribers from that instance only (so 45 subscribers using lemmy.ml accounts). But is the subscriber count from the “home” instance the true aggregation of all subscribers across the fediverse, or subscribers from that instance?

    Yes, AFAIK those stats are from each instance.
    And as far as I can see, yes, the ones in the instance were the community is hosted are across the fediverese.

    In my instance all communities from other instances only have 1 subscriber since I’m the only user.
    And the community I created in here has a count of 4 subscribers.

    I might be wrong but I think the maliciouscompliance on the lemmy.ml instance you linked is a wholy different version of maliciouscompliance than the one on lemmy.world. It’s hard to tell because the lemmy.ml one 404s for me now.

        Ok that update clears up the question lol definitely taking about the same community in both those links. My theory is that each instance is reporting the number of users in their instance that joined the community but I can’t find anything to back that up with. Good question following to see if we can get a more authoritative answer.

      Are you still looking? What would you like to know - the technical details, or what each instance feels like, or just a general “i don’t care how it works, I just want to jump into the conversation”?

        I am looking for something that goes into technical details from a developer’s perspective. How does the ActivityPub protocol structured, how one app receives data from another (e. g. Lemmy to Mastodon), how does an admin de-federates another instance etc.
