How can you make sure your Facebook profile is completely private?

[phonix265]

I switched all my privacy settings to Friends Only on my Facebook, but my sister (who's not friends with me on Facebook) tells me that she can still see all my information, my wall and my pictures. I've checked to make sure that the privacy settings are on Friends Only but she tells me she can still see all my information. Is there a way to completely make sure that your Facebook page is completely private?

Have you clicked on that padlock right under your status box? Also go to Account or Profile and look for help on your settings.

Your indentification is not private. The people who moderate facebook can see everything you do no matter what. Facebook is less private then E-mail. If you want privacy then you have to upload files at real file sharing services.

No matter what you do, there is no such thing.
