Bruce Schneider with an interesting post:
"Whenever you build a security system that relies on detection and identification, you invite the bad guys to subvert the system so it detects and identifies someone else. Sometimes this is hard -- leaving someone else's fingerprints on a crime scene is hard, as is using a mask of someone else's face to fool a guard watching a security camera -- and sometimes it's easy. But when automated systems are involved, it's often very easy. It's not just hardened criminals that try to frame each other, it's mainstream commercial interests."
"This is the arms race. Build a detection system, and the bad guys try to frame someone else. Build a detection system to detect framing, and the bad guys try to frame someone else framing someone else. Build a detection system to detect framing of framing, and well, there's no end, really. Commercial speech is on the internet to stay; we can only hope that they don't pollute the social systems we use so badly that they're no longer useful."
