I don’t fully understand how lemmy works completely yet. But for example I made an account at Division by zero and subscribe here to post. Is it not just a more inconvenient version of making a reddit account and being able to post practically anywhere?
Also what’s the difference between making an account at one instant and just making one centralized account for the social media?
Unfortunately the fediverse, at least in the Lemmy/kbin sense, doesn’t solve that particular problem. This exact scenario can still happen because a community belongs to an instance, and that instance can still be maliciously or just ineptly managed. There are also added complications with federation, defederation, instance/community politics, and just dealing with “duplicate” communities in general.
For example, certain highly political instances host many communities that are not political, and have been known to silently ban people from the whole thing just because their politics were “wrong”. Sounds Reddity to me.
Even then, you can still move the community to another instance. You won’t get the same address, but provided that the community wants to leave, it will. (In fact I’m doing this right now, migrating !linguistics@lemmy.ml into !linguistics@mander.xyz )
That’s because the community is not just some address on the URL bar. It’s the users and the content that they share with each other. It’ll be where the users are.
You can still subscribe to the community on the boogered instance from your new instance. And if it’s bad, people are going to start to subscribe to another community on the same topic on another instance with you. And it can have the same name, you don’t even have to call it r/the_true_real_feet pics like you do when a community splinters on reddit
