I will never share your information, regardless of the $$$ that I could make. When you sign up, I agree to this simple rule. I reserve the right to share with the authorities (should you violate the Big Four) any information I have on you. But I think that goes without saying.
If I have any intentions of changing anything regarding this policy, I will email you ahead of time detailing what I intend to do, how this could affect you, and a means for you to "opt out" if you so desire without losing your membership.
