Whitehouse Blame 3RD Party for Emails

Adding a checkmark to prevent someone from recieving unsolicited emails is a joke. How about requiring an email confirmation that you in fact do want to be on the Whitehouse list...and then when you click on the email link, it take you to a page with a challenge response like CAPTCHA for confirmation. The blame clearly rests on the shoulders of those in charge of Whitehouse.gov....which extends all the way to the top.
