A, B, and C are federated. They can all see each other’s posts.

New group D shows up. A, B, C, and D all start off seeing each other.

D starts posting anti-pastafarian comments. A and B are pro-pastafarian, and defederate from D.

A and B still see C posts, but now no longer see content from D. I forget if that goes both ways or not.

C thinks they should hear D out and don’t defederate, so C still sees everybody.

That’s my basic understanding at least. Politely correct me if I’m mistaken!
