On the first page Taek says:"Any file can get into storage. The clients will encrypt them first, but the network doesn't care. If you want to upload an unencrypted file (so it's available to the public), you will be able to do so. I'm not sure what you mean by "crappy" file, but it's just storage. If someone uploads a virus, it can't hurt your computer because the client doesn't open or read files, only stores them. If you try opening it with some program however, it might infect you."

So it is possible to upload stuff like rape/child porn/pirated music or movies unenrypted on my  hard drive...
I dont want  this shit on my PC.
