This reminds me of a "lawyer" who contacted my former ISP and told them they had a "court order" demanding to get my personal information. It seems I had posted something about the Church of $cientology that they didn't like. My ISP asked me about it, and I told them they better be certain that it is REALLY a court order, because if it wasn't real, I would sue them myself! I switched ISPs after that little incident. People are so paranoid when a "lawyer" sends a letter.
I have a friend locally who solved the lawsuit threat problem, which is out of control in North Carolina. Any time someone threatens/files a lawsuit against him, he automatically counter-sues. He says 99% of the time, the plaintiff drops their lawsuit.
