Poll UK eavesdropping nerve center GCHQ has developed tools to manipulate online polls, ramp up page views for articles, and obtain private photos on Facebook. That's according to Glenn Greenwald's latest trawling of documents leaked by Edward Snowden.
The surveillance agency can also, we're told, arrange calls between two selected phones, sorta like a Chatroulette for spies, and find web videos deemed to be extremist so they can be taken down. User accounts on computers can be nuked at will, and comments favored by the Establishment can be made more prominent on pages, apparently.
This information comes from a STRAP1 COMINT document, snatched by NSA whistleblower Snowden from GCHQ's internal wiki, it seems.
