I've seen some 4channer discussion [http://www.occultusterra.com/], and they honestly don't have much idea on what to do, other than the obvious (protest publicly, to your congressmen, and to your friends). I don't think they really know what they're doing this time, though. The most they have is something to screw over search engines. [http://anti-acta.com/bomb.htm]
September is in 4 days. I think I'm just going to move to South Korea in case I accidentally pirated something before I knew what I was doing.
