I wonder if it's possible to make an IRC-like chat service that that works by using social media accounts through tor to post some stenographic messages that look like real content.

For instance, pick a random subreddit, generate some comment with some markov chain based on a bunch of posts, and use that to encode communications. If each comment had a very unused word like "Methinks" at the beginning and some other strange word inside then you could probably filter out messages quite easily.

That was very interesting.

How did you find it by the way?
