facepionage 

Spying on someone via facebook. Can be done by parents, employees, peers, and others.

I don't use my real name on facebook because I'm afraid my parents will engage in facepionage.

Facebionage 

The combination of the words "Facebook" and "Espionage".
Using Facebook in order to spy on people, looking into their profile, their friends list, gathering all possible information about them.

I've done some facebionage activity last night, and guess what? As it turns out, my old friend from way back in high school is now living in Paris and he's got a new dog!
