Never use your real name or location on FB.
Even if you have to go to extreme lengths to get by them when they “insist” you do.
Actually, not using your real name on Facebook is like not using it in your day to day activities with friends. It defeats the purpose.
I have two accounts. I use the fake one for non-friend related activity.
When you post a picture to fb from a phone you give your location in gps and date of the picture.
Don’t post phone pics to the net.
