You can changed what is shown to your network though if you want to belong to the London network. Contact details are, by default, hidden to networks. Therefore either people are making it more public and risking id theft or they are adding friends who aren't really a friend but someone who is becoming a friend just to try and steal the details.
Again all an employer could see about me on facebook is the fact I'm on it, in Edinburgh and I appear to be wearing a zebra hat and scarf. That might be enough to put them off me, I don't know. Unless people are on the same networks or have changed their profile to public then that's all they'll show too.
