Interesting bit of news for the threadiverse. All three of these are fairly large lemmy instances
I thought the whole point of federation was that everything from every federated instance was connected and I only need one account to see every part of it.
No. If an instance hosts toxic communities then your instance can choose to defederate from it. You don’t have to wait for the centralized authority to ban them. It’s about being able to choose your admins and form a web of “good” communities.
