I'm sure many if not all of you know this but just in case someone doesn't....be very careful and avoid using the same email address for hobbying that you use for your FB account....put another way, never associate any of your hobby contact info with your FB account....even if you have all anon info in your hobby email profile (yahoo for example)
if you don't know, FB has an app that allows users to import email addresses (yahoo or gmail for example) into FB, and then goes and finds the owners of those email addresses in FB...most people have their real info in FB, thus the problem....someone plugs your "anon" gmail address into FB, and there's a pic of you and your SO.
I noticed this last week when FB invited me to import friends...so I imported all my gmail addresses, which are a lot of one-time real world business emails...I got FB contact info on people I've never met or just had one quick email exchange with in the past 2 years.
I use a yahoo email for hobbying with anon personal info, and that email is in no way associated with anything in my real world...especially FB!
stay safe!!
