I got into some very heated political debates on Facebook during the 2012 election campaign, and someone actually hacked into my account. I got a message from them saying that I "suspiciously logged in from North Carolina" and to change my password. I live in Virginia.
It's scary when these things happen. That's why I keep all of my sensitive information in external USB hard drives, none of it on my computer.
Like Abraham Lincoln once said, "You can't believe everything you read on the Internet."
