A PLANNED attack on Facebook by members of Anonymous isn't a hoax, but it's not clear how serious the threat is either.
A YouTube video labelled as a message from Anonymous urged hackers to help "kill" the social networking website on November 5 for supposedly abusing the privacy of users.
"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," it said.
However another message from Anonymous on Twitter denounced the video soon after it began making headlines.
Confused? Don't worry — as it turns out, so are members of Anonymous.
An Anonymous spokesman told AFP even heads of the group were uncertain how seriously to take the threat, since the loosely-knit collective doesn't have a organised 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."
The video accused Facebook of holding onto the data people post in accounts and of even sharing some of it with law enforcement agencies.
"Join the cause and kill Facebook for the sake of your own privacy," it urged.
The video has been viewed more than a million times since being posted three weeks ago.
A cadre within Anonymous was evidently trying to rally cyber warriors in a Facebook attack, but the plan did not have the backing of the majority of the group, according to the spokesman.
A message on an "Anonops" account on Twitter acknowledged some members of the group were organizing a Facebook attack, but that didn't mean the sentiment was unanimous.
