this is why instances should be abstracted away as underlying infrastructure and the users don't have to think about "instances". accounts and communities are replicated across servers.
There are a few technical problems with that. First of all, the cost of each instance would become quickly unbearable since everyone has all the duplicated data.
Second problem, a malign entity could just come, create its own instance, spam everything and everyone with ads or whatever and suddenly every instance is full of that stuff. Also, how do you handle defederating in that case?
What has been proposed before instead was to make some kind of mega communities that gather all posts from communities with the same name across instances
everyone does not have all the duplicated data. they only have the data that they need -- the data requested by a user who happens to be using some instance.
handling defederating is a good point. there could be malicious nodes that would be damaging to the network. i suppose there could be a community-mainted ledger of known malicious nodes (similar to minecraft usernames of known hackers), and the admins of the servers would maintain a blacklist. (obviously you configure that your instance's blacklist would be automatically synced with this ledger)
the mega community idea could be good. where is this being discussed?
