It is most likely because someone logged into your account one way or another and deleted your information manually. I dont think facebook will remove your info unless banned or something, which if you can log in, your not banned.
If you dont have facebook dont do it :)
If she has a Facebook or Myspace, you can look at her Relationship Status.
Its not their fault at all they give you the options to disallow people from seeing your information and being able to contact you... i dont see why anyone would blame facebook for this
i dont think so, if you dont make your content private then its obviously open for anyone to view, therefore a school/work etc has every right if view want to look on facebook to just look.
