The hacker collective Anonymous is marshalling the power of the international online community to electronically bury Norwegian killer Anders Behring Breivik’s rambling manifesto.

Breivik published his 1,500-page screed online detailing his beliefs and influences shortly before killing 76 people, most of them shot one-by-one at a youth camp on an island near Oslo on Friday

With its “Operation UnManifest,” Anonymous is asking people around the world to flood the Internet with altered, mocking versions of Breivik’s text to turn him into a “joke.”

The campaign was reported on CNET.com. A link on the hacker group’s online news aggregator flipped back to the CNET story.

The group set out six steps that start with: “Find the manifesto ‘2083 — A European Declaration of Independence.”

Then, the group said, “change it, add stupid stuff, remove parts, shop his picture, do what you like to. Republish it everywhere. Declare that the faked ones are original.

“Let Anders become a joke.”

The message ends with the Anonymous signature and the words: “We all do not forgive murder. We all do not forget the victims.”
