There are many fake Facebook accounts. If you feel they are doing something illegal then report it to Facebook.
the way that people represent themselves on the internet is often how they want to be seen and more often than not an at least slightly tainted representation of who they 'really' are. I guess what you should do is use how they are on facebook as a guide of how they'd like to be seen and keep it in mind, but if you know them outside facebook then the person that you know in the real world, is the real person and who you should think of them as.
Ask your friend if you can log on to his/her facebook and message facebook.
You can put a mail from Facebook fan page to a contact person by simply synchronizing your person contacts and Facebook contacts.
