Ok, As I was reviewing a spam domain to submit, I ran across a somewhat disgusting policy I felt the need to share with everyone here.
Here is a snipplet:
" Additionally, when you open, preview or click on the advertising portion of our e-mails and/or those of our marketing partners and/or affiliates of GroovyUSA, you have agreed to the terms set forth in our Privacy Policy and agree that as a function of opening, previewing or clicking on the advertising portion of our e-mails, that you will receive new or additional marketing communications from us, our marketing partners and/or affiliates of GroovyUSA. " Right before this, they talk about using clear 1 pixel gifs to track what you view, so they are saying, if you view this message, we will send you more and you accept for us to do whatever we want with your information. http://www.groovyusa-MUNGED.net/ Click on the privacy button at the top of the page.
