@luka2323,
Like other person said.... your friend should call facebook and provide details that is only within their account and that being said facebook, along with
Google
Yahoo
Twitter
Indeed
Linked In
Your Bank without signing that document to prevent selling of information.
Collects information you provide, sells it to private companies, organizations, etc, In which have mail-in-advertisements, to creating a profile ( like police profile or CIA/FBI/HLS/NSA profile or permanent record profile ) on you in which various agencies could act on them.
Honestly I do not have any facebook account in "my name". I never will.
