In this digital world where everything seems to be vulnerable, how can one be quiet a bit anonymous?
Well facebook is of US intelligence, a spy machine (according to Julian Assange).
Google has backdoor access to its systems (remember the chinese hackers article?)
Tor is again of the US intelligence (some article on HN).
Intelligence agencies can easily map ip addresses on google database with those same ip address used for accessing facebook.
Just a curious thought!
