How does one hack an email account? I don't know much about hacking, but I thought in this day and age running scripts and all that kind of stuff didn't get you anywhere with an email account on a big provider like Hotmail/google. You need to be able to work out the password to get in. And if your password isn't easily guess, or you haven't given it away during conversation, then they know it by other means ... and those are likely to be key loggers on your computer, or something similar.
Would recommend using complex passwords, and doing a thorough scan for viruses and Trojans. Also, never replying to things like "What's your porn star name? Combine your first pets name with your mother's maiden name, and that's your porn star name." kind of shit on facebook. They're just scams to get answers to security questions out of people.
Also stab everyone you know to death. That'll also help.
