Ken Popehat (http://www.popehat.com/) might be worth contacting. Even if he can't help directly, he might know someone who can. He's about the closest thing the internet has to a folk superhero in law; he has a "Popehat signal" (http://www.popehat.com/tag/popehat-signal/) he uses for a "call for pro bono help for online folks who get threatened with bogus censorious lawsuits" (http://www.reddit.com/r/IAmA/comments/1aokls/iama_federal_cr...) and he got involved, at least twice, with a university-area bus company that has tried to silence criticism on Reddit (http://beta.slashdot.org/story/185659).
