mikejuk writes "Following the successful defense of the Internet against SOPA, website owners are being invited to sign up to a project that will enable them to participate in future protest campaign, the Internet Defense League. The banner logo for the 'bat-signal' site is a cat, a reference to Ethan Zuckerman's cute cat theory of digital activism. The idea is that sites would respond to the call to "defend the Internet" by joining a group blackout or getting users to sign petitions. From the article: 'Website owners can sign up on the IDL website to add a bit of code to their sites (or receive code by email at the time of a campaign) that can be triggered in the case of a crisis like SOPA. This would add an "activist call-to-action" to all participating sites - such as a banner asking users to sign petitions, or in extreme cases blackout the site, as proved effective in the SOPA/PIPA protest of January 2012.'"
