It's interesting how "fake" you can make your profile. It's your profile, after all.
You start by changing your name, picture, location and everything. But as long as you want to use Facebook, you must connect with your real friends. And visible friendship connections are pretty much the thing in Facebook. Unless your friends and their friends all operate under pseudonyms, it's rather easy to track someone who's known by someone.
If your profile is totally fake then it has nothing to do with your real life.
