WHAT was supposed to be a mass-murderer's legacy is about to be obscured forever on the internet.

Shortly before his horrific attacks, Norwegian killer Anders Behring Breivik published a 1500-page manifesto on the web outlining his motives and beliefs.

"I ask that you distribute this book to everyone you know," Breivik wrote in the introduction.

Now, a group of online activists are about to do just that — though perhaps not in the way the killer anticipated.



Anonymous has called on internet citizens to destroy Breivik's legacy by creating altered versions of the text which mock the author and promoting them as the real document.

Through an exercise titled "Operation UnManifest", the group hopes that, eventually, no one will be able to figure out which manifesto is the original.



"Anders Behring Breivik wants to use the cruel action of killing over 90 young people to promote his 1516-page manifesto," says a message posted online.



"Anonymous suggests:



"1. Find the manifesto of Anders Behring Breivik: '2083 - A European Declaration of Independence'.



"2. Change it, add stupid stuff, remove parts, shop his picture, do what you like to.



"3. Republish it everywhere and up vote releases from other people, declare that the faked ones are original.



"4. Let Anders become a joke, such that nobody will take him serious anymore.



"5. Spread this message around the internet and real life, translate it.



"6. Have a moment for the victims of his cruel attacks."



The note ends: "We all are anonymous, We all are Legion, We all do not forgive murder, We all do not forget the victims."
