Why do I have multiple banned users on my instance, when I never blocked anyone?

I started to notice that I have multiple banned users on my instance, even though I have never banned anyone. And that number is increasing.

  • Did your instance suffer from yesterday's script kiddie hack?

    • Not sure, but the users were being added immediately after I created the instance. Which is about a week ago.

      • You mean in the admin interface? That's normal. User's banned on OTHER instances will appear there.

        • I see, does it means that they are also banned from my instance? Or how do I read it?

          • No, they aren't, because accounts aren't federated. They're effectively banned from the fediverse, though, since once an account is banned, that very account can't be used to access the fediverse any more. Nothing hinders them to recreate the same accounts on other instaces.

            I think, this is really misleading and also UI / UX wise pretty bad, as it clogs up the entire admin panel.

            • I see, since they're banned on their instance, that means they cannot access their account and then even the fediverse. Alright, thank you for the explanation. Helped me a lot.

            • Wait, isn't a ban just for one instance? You say it's not federated, so...?

              I mean, if any ban was network-wide, it means a malicious instance can start banning anyone for no reason, and prevent those users from interacting at all?

              Also aren't instances supposed to have their own rules?

              • No. What I'm talking about is:

                • You register an account "WhoRoger" on "lemmy.world"
                • You're banned from lemmy.world
                • Ban appears everywhere (don't really know why)
                • You can't use WhoRoger@lemmy.world anywhere any more
                • But you can register "WhoRoger" on any other instance and use that again
                • Ok but what if I get a ban on lemmy.xyz, will that affect other instances?

                  Cause I think that's what OP is talking about, that their users got banned on other instances, not their home one.

                  • Yes. The users banned on other instances will not be able to access his / her / their instance from their home instance, as they're banned there. Sorry, I'm usually trying to explain myself way too complicated.

                    • I'm just more confused now to be honest. I'm not doing the best job either.

                      Let's have instances H, A and B. The user's home instance is H.

                      If the user gets a ban on any of these, how will it affect their use of other instances?

                      So,

                      Ban on H: ...

                      Ban on A: ...

                      Ban on B: ...

                      (Ofc A and B are the same, but gotta have 3 instances to know the effect on the 3rd one.)

                      • Hmm. So, right now, you could totally post in one of the communities on my instance, right? If I ban you, you can't do that any more, but you'll still be able to post everywhere else. But if lemmy.world bans your account, that very account can't be used to post anywhere any more.

                        You'd have to register somewhere else.

                      • If your home instance is H and you're banned on H, you're banned everywhere.

                        If your home instance is H and you're banned in A, you can't interact with A.

                        If your home instance is H and you're banned in A, B gets a wanted poster from A but B's not required to arrest them.
