It seems that using email or social networks, nothing is actually private. The Atlantic Wire reports:
Twitter has released its second biannual Transparency Report and — what do you know? — Twitter is still giving away more user information requested by the U.S. government than ever, and without a warrant.
Twitter got 815 total requests in the last six months, and more than 80 percent of the U.S. government’s asks on user data came without a warrant. Google, too, has seen an uptick in government requests, reporting a total 21,389 requests for information in 2012.
U.S. officials are asking for more of what we’re doing from more of our daily Internet activities — typically without getting a court’s permission. Google, however, is lobbying [for better privacy protection], and this year the Senate will vote on an updated version of the Electronic Communications Privacy Act that requires a warrant for all email and private communication stored over the cloud.
