FILE - A Jan. 3, 2011, file photo shows the Facebook headquarters in Palo Alto, Calif. More young people these days say they've had their Internet accounts hacked or spied on. Many also say they know who did it and don't seem too bothered. An Associated Press-MTV poll finds 3 in 10 teens and young adults have had people log on to their Facebook, Twitter, MySpace or other Internet accounts and either impersonate or spy on them. That's nearly double the level seen in 2009. (AP Photo/Paul Sakuma, File)
