I’m plagued by visions of Dark Reunion stealing Black Beat, the unstoppable force that lives in my right arm.

But they will fail again, as they always have, for I am The Jet-Black Wings, protector of this world and I see right through their evil schemes!

Not an expert, just relaying what I read elsewhere. TLDR: “nothing goes in, nothing goes out between you two” is about right, but it’s not entirely symmetrical.

Instance A defederates from instance B. This means that (let instance C be a neutral third party that is federated with both A and B):

• no posts or comments by users from B anywhere on lemmy are visible to users from A
• existing posts and comments in communities on A are still visible to users from B
• new posts and comments by users from A and C in communities on A are not visible to users from B
• new comments by users from B to existing posts in communities on A are not visible to users from C
• new and existing posts and comments by users from A in communities on C are still visible to users from B

Discombobulate.

The latest version (0.0.35) is out already and has this feature. So far it’s only on github I think, but you could install it from that apk if you can’t wait for the play store release.

Some other things might be broken (default sort no longer seems to be remembered for instance) and you’ll have trouble connecting to instances that are not yet on lemmy 0.18 (this might be the majority currently; lemmy.ml is a big one that already updated), but apart from that, it’s looking good.
