I've seen that but the problem is you rely on other people to "unsubscribe" from you. I want to be the one to control what is visible! And although facebook say they have simplified privacy settings, I still get confused. People are saying it's all information that's open to view anyway on your profile but I still don't like it. I think I have made it as private as I possibly can, other than making myself unsearchable which I will be doing in the very near future. I think a "friend" culling is in order as well!
