Jeremiah Cornelius writes "According to a report by the Associated Press, protesters have been stopped in their tracks after Facebook aided Israel in cracking down on the group of activists from the UK, France, and Belgium who planned their event using the popular social networking site. Facebook allowed government agents to track the activists activities and then create a black-list of people who participated in the planning of the protests. The black-listed group was then forwarded to airlines with instructions to prevent the activists from boarding air flights to Israel. Over 200 activists were prevented from flying after being added to the airlines terrorism watch list, according the the AP report. Was Julian Assange correct, when he warned that Facebook was a giant, 'appalling spy machine'?"
