Pinterest changes it's terms which is probably due to the fact that many complained about the part where Pinterest reserved the right to sell your images. Here are the basic highlights of the term changes.
* 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 updated our Acceptable Use Policy and we will not allow pins that explicitly encourage self-harm or self-abuse.
* We released simpler tools for anyone to report alleged copyright or trademark infringements.
* Finally, we added language that will pave the way for new features such as a Pinterest API and Private Pinboards.
