faceabotage
The act of making your Facebook look like a disaster. It's done by people who think they're helping but are really just messing with you.
Your friend posted a photo of your face with a dog mask and called it 'your new look'.
Your roommate added 100 fake friends to your profile and tagged them all in a random photo.
Your friend changed your status to 'I am a ghost' and won't let you back to normal.
