It is a noble effort, but you still have the same dilemma:

* if only few people is using it, then the messages will be lost

* if somehow this gain popularity, then the authority will ban it

For a small determined group, there are already easier ways to communicate.

Yes. What I'm targeting is the mass population, and I really need to figure out a way to solve this dilemma.
