You guys are more retarded than I thought.
Facebook has 750 million members. That's 3/4ths of a billion. There are on average, 375 million people logging onto facebook every day. Facebook isn't going to be taken down by a DDoS, because they literally can not provide enough bandwidth to incapacitate the site. There's not way. Even if a 10 thousand people were running LOIC, and aiming it at facebook, they would be generating about the same amount of traffic as a few million people. The difference between 375 million, and 380 million, isn't even noticeable to facebook. They have the capacity for each of their users to be online at the same time, you could double the amount of people who go on everyday, and still not have facebook go offline.
Now, I understand people like Jester don't just use LOIC and are actual hackers, they use different sorts of tools. But even then, facebook is the 3rd largest user of bandwidth in the world, and has incredible amounts of protection. Facebook itself releases information like no other, it leaks constantly. But, the actual servers are so protected it would be incredibly difficult to take them down for even a day.
Please, stop talking about shit you have no idea about. Anonymous is a group of script kiddies who don't do anything. There are a few people, like Jester and GeoHot, who actually know how to do things and get them done.
