The RIAA is made of complete idiots! They have no clue what to do about file sharing. Their so called "spoofing" could help but they won't do it at the level they need to in order to make anyone care. This almost beats them trying to sue At&t and Cable & Wireless for allowing people to visit music pirating sites!
Just so you know, the average record label president has little or nothing to do with the RIAA. The RIAA is kinda like a demented old uncle that you acknowledge but you don't speak to much because he's crazy. Strange but true.
