Try this, Have a FB Acct for the most trusted immediate family and friends that are 'as good as family. Use a pseudonym - not your real name - after all, who was Sam Clemmens. Lock this down to friends only.
Next, have a different FB acct with a different name for friends and acquaintences. This can be more open.
Next, have a Linkedin acct with a real (or professional) name for business colleagues, professional contacts, etc.
DO NOT intermix any combination of the above. i.e., none should be 'friends' with each other. Also, no friend should be a friend on any more than one acct.
If you are a professional person, a 2nd Linkedin acct is a good idea also. One should be extremely 'Squeeky Clean'. Remember, society will judge you by the company you keep (friends) at least as much as by your own actions. Have something that you can be proud to show your potential employer and client.
