The hacker collective Anonymous has vowed to 'destroy' Facebook on Nov. 5, as Facebook is "selling information to government agencies" and "giving clandestine access to information security firms," according to a YouTube video.

"Everything you do on Facebook stays on Facebook regardless of your "privacy" settings, and deleting your account is impossible, even if you "delete" your account, all your personal info stays on Facebook and can be recovered at any time. Changing the privacy settings to make your Facebook account more "private" is also a delusion. Facebook knows more about you than your family," Anonymous said.

In addition, Anonymous has blamed governments saying, "Facebook 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 these so-called white hat infosec firms are working for authoritarian governments, such as those of Egypt and Syria."

"If you are a willing hacktivist or a guy who just wants to protect the freedom of information then join the cause and kill Facebook for the sake of your own privacy," Anonymous said, urging people to join the anti-Facebook operation.

Anonymous said this is a battle for choice and informed consent. Although, Facebook kept saying that it gives users choices, Anonymous said it is "completely false."

The hacker collective promised that Facebook will go down on Nov. 5. And it believed the operation is right and people will appreciate them for doing the 'good work.'

Facebook has not responded to Anonymous' threat. One of Facebook's spokesman declined to comment on Anonymous' provocative release.

The declaration ended with the group's symbolic signature, "We are anonymous. We are legion. We do not forgive. We do not forget. Expect us."

Anonymous had attacked some major websites in the past. The group has taken credit for hacking into PayPal, Master Card, Visa and the Church of Scientology network.

The group has also tried to take down another Web giant Amazon last December but failed. Amazon incidentally had booted WikiLeaks from its web and Facebook has followed suit.

Meanwhile, Business Insider reported that Google+ (or Google Plus) had removed Anonymous' profile and deleted its Gmail account but the group quickly launched AnonPlus.com.

Nov. 5 is Guy Fawkes Day or Guy Fawkes Night. Its history can be traced back to the events of 5 November 1605, when Guy Fawkes was caught guarding explosives placed beneath the House of Lords and was arrested. Guy Fawkes was a conspirator in the Gunpowder Plot.
