I found this and thought it was an interesting article. Another case, even though this person was wrongly accused, of someone who is not afraid to fight back and filed a class-action lawsuit.

Quote
On 07/05/2012 Henry and Associates, PLLC, a lawfirm from Louisville, Kentucky, filed a class action lawsuit against five porno purveyors — well-known copyright trolls. The lawsuit is filed on behalf of Jennifer Barker, one of the victims who did not want to forgive an unprovoked assault by a copyright troll lawyer M. Keith Lipscomb. Lipscomb is one of the most cynical and productive trolls, whose “portfolio” comprises hundreds, if not thousands of trolling lawsuits. He is also one of the few trolls who abuse the Florida’s Pure Bill of Discovery to unjustly enrich himself and his crime partners.
