Members of a group of activist hackers known as Anonymous say they're planning to "kill Facebook" because the popular social networking site purportedly abuses the privacy of users.

In a video uploaded to YouTube, a digitized voice announces that "Operation Facebook" will take place Nov. 5 and issues an appeal to "join the cause and kill Facebook for your own privacy."

The video claims that the California-based company "has been selling information to government agencies and giving clandestine access to information security firms so that they can spy on people from all around the world."

Some of the security firms work for authoritarian regimes such as those in Egypt and Syria, the voice claims.

About 1.2 million people have viewed the video on YouTube since it was uploaded on July 16.

Anonymous confirmed via Twitter on Tuesday that only some members of the group are organizing the Facebook attack, and that "does not necessarily mean that all of Anonymous agrees with it."
