According to a quick bit of Google-Fu, Facebook alone has 300 petabytes of data and adds another 4 petabytes per day, contains 250 billion photographs which grows at a rate of 350 million per day, has nearly 1.5 billion daily active users/2 billion monthly users and growing fast, etc. - which apparently all need scanning and judging automagically to somehow always agree with the government?
Oh look, a flying pig... Haha.
