 * 1) * 2012, Michael Kaemingk, "SOPA bill fails to address actual piracy issues", The Spectator (Seattle University), 25 January 2012:
 * My own personal hell came to pass on January 18th, 2012: Reddit and Wikipedia went offline. Yes, the point was to raise awareness about the intrusive, unjust Stop Online Piracy act. And yes, the blackout was politically influential and reached millions over a period of twelve hours…but what was I supposed to do? Play in the snow? Actually talk to humans in real life? What is this I don't even.
