If the content is uploaded encrypted and the operator doesn't know the key, then they don't know what they are storing, so they can't be blamed for what they're hosting anymore than Dropbox can be blamed if someone dumps a Truecrypt file on their servers and LE finds out that file contains illegal content. Of course, if that's true, they can't censor it either. I mean, Dropbox could reject all Truecrypt files but an EKS server would be designed to store encrypted content. The thing about dumping old content, I consider that a feature. Look at this forum. Why store every thread since the beginning, when everyone asks the same questions over and over every week? The popular threads stay on the front page for weeks or months at a time, so they are safe. It would work just as well if it was designed like 4chan to roll old threads off the server, say after 3 months of inactivity. Hell, it even warns you not to dig old threads back up and to start a new thread! It is needlessly storing gigabytes of data. Yep, that's what the Tor people keep saying.
