Stopping the spread of CP through any means

How would I go about writing a virus that takes down CP websites? I know C and perl, but I've never written a virus or done any Greyhat things before. I'm not asking for a tutorial, but just a few pointers in the right direction to start learning.

Thanks in advanced for the advice.

There are no ads on CP sites. There are no commercial CP sites. That's fucking retarded. Only old people buy CP and that's on VHS from the mafia.
