A splinter group from the notorious hacker collective Anonymous is rumoured to be gathering support for a plan to “kill” online social networking giant Facebook.
A YouTube video labelled as a message from Anonymous claimed that “Operation Facebook” would take place on November 5. its aim was to destroy the social network on the grounds that it abused the privacy of users, the video said.
But an Anonymous spokesman told AFP that even heads of the group were uncertain how seriously to take the threat since the loosely-knit organisation doesn’t have a strict command structure and members mask their identities.
“I found groups of people who say we absolutely are and have a trick up our sleeves,” said the spokesman. “I found others that say it isn’t us and that this is stupid.”
