I am thinking of an app that could allow people to share text so they can post grievances about a totalitarian government in a p2p network. It has to be p2p because a website can be blocked. This would be for locals to post about their mayor or the neighborhood cop. Let's not worry about social engineering, let's only worry about the technical side of it.
Is it possible to 100% obfuscate the origin of the message creator? I know that TOR is not 100% secure. I imagine something like if someone were to send a message from a burner phone or the message is encrypted and split into multiple places then reassembled later. Meanwhile, the reader's origin doesn't need to be 100% obfuscated since they can't arrest millions of people just for reading it. They only want to catch the message creator.
The obfuscation of the original sender is paramount because without that, people would be too afraid to post anything. Right now there are always dissenters, but they are few and they post to places like facebook. Then eventually they get arrested.
Also the service should only allow text because there is potential for governments to introduce CP into it to destroy the legitimacy of it.
Do any of you know of an app like that? Would any of you be interested in modifying a TOR client to allow easy access to location based message boards?
