If my home instance defederated from another, can I still post to the other instance? What about posting to an instance which has been defederated from my home instance? - Lemmy.world

Let’s use lemmygrad.ml [http://lemmygrad.ml] as an example. My home instance is lemmy.world, which I see has defederated from lemmygrad.ml [http://lemmygrad.ml]. If I post to a community on lemmygrad.ml [http://lemmygrad.ml], will everyone be able to see it? What if the opposite is true? What if lemmygrad.ml [http://lemmygrad.ml] is the one who defederated from lemmy.world, and not the other way around as in the above example? I’m just a little confused by how federation works. I know that I won’t see lemmygrad.ml [http://lemmygrad.ml] posts on my All feed due to defederation, regardless of who defederates with whom.
