The plugin adds small protest box to your website. By default it’s collapsed, but once clicked, the “Stop SOPA” box appears.
On settings page you can specify the position of the protest box: either at the right bottom corner or at the middle right edge. 
You also can turn on/off “Blackout Day” option. In this case website will show black screen (click demo link below to view the screenshot) and return 503 status (no problems with search engines) on 18th January 2012, 8:00AM – 8:00PM (server time).
By placing this box on our WordPress websites we are protesting against of SOPA.
You can see demo here: <a href="http://www.icprojects.net/stop-sopa.html" rel="nofollow ugc">Stop SOPA</a>.
