Stop your employer from finding your facebook without doing that to friends

1. Use a different e-mail address to register for facebook or other social networking sites as the e-mail is a unique identifier of which John smith you are. so in resume use your more formal one or a different one.
2. In resume use your whole full name as its a document. for facebook registering only use your first and last name so friends can still find you.
3. Your friends might not be able filter find you though if you don't place your fully name so join some networks like high schools, etc. where you meet your friend(s)
