when facebook redid all of their facebook pricvacy settings some of your settings may have changed without you knowing. I know they prompted people to fix the settings but there was still info that i only wanted friends to see that was set to "Everyone"
Make sure you go into privacy settings and also into the photo privacy settings as well!
I noticed that i could see a lot of peoples profiles and all their info even if i wasn't friends with them. I also checked my one friends profile from Serg's account and was able to see all her info (email, phone, about me, work, education) even though he is not a facebook friend of hers, she said her settings were set to "everyone"
