EUA usando redes sociais para derrubar governos e manipular opinião pública dos países.
In 2011 it came to light that the U.S. military had developed a 'sock puppet' software for creating and managing fake online identities. These sock puppet accounts were to be used to spread propaganda on social media sites, forums and blogs. The software which was described as an "online persona management service" allows one soldier to control up to 10 separate identities based all over the world. When this program was exposed the U.S. government claimed that the program was never used on English speaking audiences. Considering that these are the same people who swore up and down that the NSA surveillance program never targeted U.S. citizens, we can take that with a grain of salt, but it's worth noting that they explicitly acknowledged in their statement that the program was intended for covert operations in foreign countries.
A leaked document recently made public by Glenn Greenwald showed that the UK's GCHQ has been running a similar program through a unit called the Joint Threat Research Intelligence Group (or JTRIG). According to the documents, JTRIG relies on two primary tactics: (1) the injection of false material onto the internet in order to destroy the reputation of its targets; and (2) the use of social sciences and other techniques to manipulate online discourse and activism towards desired outcomes. Among the methods promoted in the document were "false flag operations" (posting material to the internet and falsely attributing it to someone else), fake victim blog posts (pretending to be a victim of the individual whose reputation they want to destroy), posting “negative information” on various forums, luring targets into sexual encounters to destroy their reputations (honey-traps), sending emails and text messages to the target's friends, neighbors and coworkers, and “crafting messaging campaigns to go ‘viral’."
