I'm not sure, I've never run such a site myself. Maybe someone behind 7 proxies could explain? I do think this could be solved, with for instance public-key addressed content (e.g., a DHT where the content is references to files, addressed by pubkey and muteable only to the owner of the corresponding private key). I've been trying to figure out why this isn't done in practice for a while now. Maybe it's a selection bias, where all dark file distribution networks run that well/securely drop off the map completely?
