No one is safe from infringing on Viacom's copyrights. Take this latest example, from BoingBoing:
Christopher Knight made three commercials as part of his campaign to run for a seat on the Rockingham County Board of Education. He posted them on YouTube. Viacom's VH1 ran one of the commercials on its show Web Junk 2.0, without seeking Knight's permission. Knight then posted the Web Junk 2.0 segment on YouTube. Yesterday, YouTube pulled the clip, at the request of Viacom, which said Knight was infringing on its copyright.
