The American journalist and founder of 'The Intercept', Glenn Greenwald,  explained why Snowden is not registered in Facebook. "No one should use Facebok" he recommends.

Glenn Greenwald, author of articles in the Guardian (US) regarding the documents leaked by Edward Snowden and the founder of 'The Intercept', participated this week in a Q & A in Canada, in which he explained why his colleague and former employee of NSA does not have a Facebook account.

"This is one of the worst violators of privacy in history," Greenwald said during the presentation. And rightly so. "Nobody should use Facebook," he added.

The reporter noted that in Russia, Snowden can still follow his normal life, since the country allowed him to continue his public life and reveal more facts about the US surveillance. "Edward became an important voice in the debate that he helped to catalyze, so he is very happy," Greenwald said.

Facebook is known, among other things, to control everything their users share and do, and where they are. Basically nothing get deleted or 'forgotten'. The demands of the global social network for access to personal information and censorship are increasing surveillance. Previously, Snowden lashed Dropbox and other services, including Facebook, because they violate the privacy which he pointed as one of the main points of global spying today.
