as per their email:
Over the last few weeks, we've been working on an update to our Terms. When we first launched Pinterest, we used a standard set of Terms. We think that the updated Terms of Service, Acceptable Use Policy, and Privacy Policy are easier to understand and better reflect the direction our company is headed in the future. We'd encourage you to read these changes in their entirety, but we thought there were a few changes worth noting.
Our original Terms stated that by posting content to Pinterest you grant Pinterest the right for to sell your content. Selling content was never our intention and we removed this from our updated Terms.We think these changes are important and we encourage you to review the new documents here. These terms will go into effect for all users on April 6, 2012.
Like everything at Pinterest, these updates are a work in progress that we will continue to improve upon. We're working hard to make Pinterest the best place for you to find inspiration from people who share your interest. We've gotten a lot of help from our community as we've crafted these Terms.
Thanks!
Ben & the Pinterest Team
