i run 3 facebook accounts.
my real --private one is strictly for family and personal friends only--i mean--people i know well in real life. even then my settings are that only i can see these friends--no one else can.
my ex jw site is stan livedeath--and i have 100's of internet friends on it. all visible to each other. so--be aware of that if you befriend me.
my 3rd is a private one i set up to chat to my partner-----but annoyingly the FB phone messenger facility only works with a/c one.
