Unfortunately mail server reputation's based on how rich and important you are and not how much spam you send

Considering I get spam from large U.S. companies because they believed someone else when they used my email to sign up for something, I am inclined to agree with you. No matter how many times I click "mark as spam" in Gmail, it always gets delivered to my inbox.

Credit Karma is the biggest offender off the top of my head. For a company in the consumer datamining business, they sure aren't doing a good job.
