A person is gone from my friend list. Old notes are still showing, but the name is grey. I can't find them anywhere else. When logged out, if I search for them in Google the error "page not found, link expired" comes up. However, I had someone else look for them the same way (this person does NOT have the facebook) and they found their profile through Google just fine. How can this be? What happened? Even if they blocked me, how come I cannot see their basic profile under Google when logged off?
