I believe it depends on your privacy settings, but if you look at someone's profile, FB will generate a "You May Know. " friend suggestion to the other party. A 20-something is likely to figure it out if she starts getting friend suggestions for 60-something men.
[QUOTE=FarFarAway;4365837]I am indebted to my bowlbuddy for turning me onto this. Facebook messenger is a standalone app. I happened to have it on my Android phone from the word go, but never fired it up. When I did, it looked into my contacts, where I have entered every girl who gave me her #. I was not required to give my own FB info, of which I have none for sugaring. Only my real profile, which of course I *never* want to cross into my sugar life. Anyway, the app goes through the phone #s and gives the FB usernames of all the girls it recognizes. That means real first and last names mostly. Sometimes it also give locations, occupations, etc, whatever might be on her FB page. Since I am doing this on my burner that doesn't include any of my real identity, I think this is safe. Provided I don't "wave" at any girl on my phone, I don't think she'll even know I found this out. I have also found some numbers that were from girls, supposedly, but then a guy's name is on messenger. Those I blocked.[/QUOTE]
