Global hackers group, Anonymous, has issued a threat to take down Facebook on November 5, 2011 aka Guy Fawkes Day. While it’s well documented that I’m not a fan of going “all in” on a third party web site, this could cause major headaches for brands launching or planning to launch holiday promotions via the social network. More after the jump.

Below is the video posted on YouTube, using a War Games-esque SAM speech synthesizer and some cryptic images:

The group has already taken shots at PayPal, Visa, Amazon, Bank of America, and most recently the Syrian Ministry of Defense web site, and has set its sights on Facebook over – you guessed it – privacy.

Why are they doing this? Per their video:

“Facebook has been selling information to government agencies and given clandestine access to information security firms so they can spy on people from all around the world.”

“Everything you do on Facebook stays on Facebook regardless of your privacy settings. And deleting your account is impossible. Even if you delete you account all of 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.”
