Could you elaborate a little? I think I've got a reasonable handle on how Lemmy works across instances, but there are still a couple of things that I haven't grasped just yet.

User accounts - I have accounts with the same username across 3 or 4 different instances at this point. I'm still yet to grasp how a ban would work in the fediverse, or who would ultimately be responsible for a global ban. If I were banned for posting piracy related content on one instance, would that just mean that I can no longer participate on that particular instance? That nobody from that instance could see my posted content from other instances? Would all of my content disappear altogether? Is there some sort of link between my accounts given that they have the same username?

It's all quite confusing on that front.

Overarching powers - is the banhammer truly localised, or is there an over-arching censor power that could wipe out a user across multiple instances at once?

Thanks to anyone who can help to answer.

Let's say you're on your lemmy.ml account, and you get banned from the lemmy.dbzer0.com instance, you would just be banned from that instance not all instances. But if you got banned on lemmy.ml from lemmy.ml then you'd lose access to that account. Alternatively, you can also get banned on a community level as well. In regard to your accounts with the same name between instances there is no link, they are entirely separate.
