I honestly don't know what to think. Here're some points to think about:
1) CP is bad (m'kay?) No, I'm serious this time. It's good to see Anonymous is going after that.
2) From the other side, it seems like a cheap publicity stunt from their side to gain popularity.
3) Also, I can't help but notice that, although despotism of a superior entity with right moral beliefs is the only efficient means of a just government, I cannot trust Anonymous' beliefs to be right.
4) Hell, I don't even see why should anyone agree to them doing it... CP is bad, but they're given way too much freedom to mess around on the net.
