Do I have a course of action against them? No, the judge and or jury would basically tell me to go fuck myself and if I don't like it, I should endeavor to keep my big yap shut in future, lest it happen again.  Actually, I can think of a couple of arguable causes of action. The real problem when law intersects with the internet isn't so much causes of action as it is enforcement. A court order, without a means to enforce it, is just a piece of paper. It's really hard to enforce court orders across state boundaries and even harder (almost impossible) internationally.  People run off to their local courthouses all the time over disputes with their neighbours or family or whatever because they love the drama and have nothing better to do. They want to do the same thing on the internet but the issue is that the complex legal framework and the costs associated with inter-jurisdictional enforcement mean its only worthwhile for big money judgments. Getting a court order is pretty easy. But then what?
