Huh. Thanks for answering. But this kind of breaks the intentions of a federated construct, doesn’t it?

In the worst case, I’d just block people from that instance, but not defederate it. That way my users could still interact with their community but their users couldn’t disrupt my instance.

Many smaller instances have defederated from lemmy.world, for example

Why?

Yeah, I assume if they took down Wikipedia itself then hundreds of copies would pop up all over the place, probably hosted elsewhere, and one of them would become the primary replacement over time.
Media might be lost to some extent, but I doubt there’s any way you can take the text/information/metadata off the internet at all, and that’s the most important aspect.

Wouldn’t be surprised if the kid playing on the mat would be part of the print as well.
