Interesting. I don't understand why you would do this though. I understand why criminals or people will malicious intent would love a service like this but I don't understand what makes someone create a business from such uses.

You have in your FAQ, "We will NEVER expose your real phone number or your call history to anyone but you. That is our promise." So you are not going to reveal anything to the FBI, CIA, Homeland Security, etc? That's a bold statement.
