Sure let's get John and Jane Doe to acquire a secure crypto, securely access a website over Tor, and manage to maintain OPSEC. Then we can have them setup their own Dropbox clone with rsync and some trivial bash scripts!

Alternatively, we can create an easy-to-use site for the common man who is willing to pony up some petty cash for whatever their version of "justice" is. At sufficiently high levels, in sufficiently corrupt societies they can trace things down and disappear you. This idea isn't for those places, and likely wouldn't even work anyway.

However, in nations with reasonably sound rule of law this could potentially work.
