For several years now, the U.S. Central Intelligence Agency (CIA) has had a special unit for monitoring social networks all over the world. The official name of this bureau is “Open Source Center”. Its employees are mostly hackers and linguists.
The primary goal of the bureau is the collection, filtration and analysis of information coming from social networks, as well as local forums, TV channels and other mass media. The reports of the bureau go directly to the White House.
Linguists and professional hackers from OSC are capable of filtering millions of posts in Twitter alone and finding information that others don’t have a clue about.
The bureau was created after 9/11 and the official reason for this was, obviously, “war on terrorism”.
