Bump. Saw this video and decided to resurrect this thread. So anyways, I'm not sure how serious Anonymous is about hacking FB, and I think if they did do it they are capable of doing something as large-scale as that, but I don't know why they'd give FB notice months in advance that they are going to do it, as I'm sure FB will spend a lot of time now upgrading their security to prepare for it, credible threat or not. I've had my FB deactivated on and off again for a few months now, and I'm sure I'll deactivate it again before Nov. 5th, but I highly doubt that will do anything to protect my security since FB probably has all my info already. Either way, if Anonymous succeeds in shutting FB down, either temporarily or forever, I probably won't miss it too much. All my important friends got my number anyways, so it won't be the end of the world.
And here's the video, btw.
