Anybody read about the elderly couple threatened by Atari when it was claimed the couple had downloaded Race 07? They didn't want to listen, claimed they had an IP address that proved they'd been downloading Race 07, and only rescinded the claim when a magazine intervened. It's crazy what companies can get away with.
