In December 2011, shortly after students created a petition to lower tuition at Arizona State University (ASU) on the petition website Change.org, ASU blocked access to the website on its network. When the censorship of the site gained widespread attention, ASU explained its actions by citing concerns about "spamming" emails from the site related to the petition. In February 2012, following a national outcry and within hours after ²ÝÝ®ÊÓƵAPP¹ÙÍø sent a letter criticizing the censorship, ASU eliminated the Change.org filter.
