On feddit.de, lemmy.world is only temporarily defederated because of CSAM until a patch is merged into Lemmy that prevents images from being downloaded to your own instance.
So I'll just be patient and wait. It's understandable the admins don't want to get problems with law enforcement.
It would be less of a problem if we as users on an instance could block entire instances, effectively defederating it just for our user. Then those running instances could defederate only in severe cases.
