Just happened to me today on FB:
Hacker: our return flight leaves in some few hours but we are having problems settling the hotel bills
Hacker: i need you to please loan us some money so we can settle the bills
Hacker: i promise to refund it as soon as i get back
Friend: what is your phone number
Hacker: my phone was stolen in the process
Friend: what is the hotel number
Hacker: it has been so terrible for me here
Friend: do you want to speak to the hotel manager?
Hacker: I can but I am in a meeting till 11am
Friend: give me the number and I will call
Hacker: have to get out of facebook
Friend: send me the phone number
Hacker: the best way for you to help me out of here is to help me send some money via western union
Hacker: i need you to send the money via western union,,,all you need to send the money is my name and location
Hacker: Name:<My Name>
Hacker: Location:96 Trongate
Hacker: Glasgow, G1 5EP
Hacker: that is all you need to send the money
Hacker: you can also have the money sent online or find a western union location
Hacker: here is the hotel manager's number
Hacker: +447024064345
Hacker: i might not be on facebook when your done, you can contact me on my mailbox... (<incorrect nearly my e-mail).
What all of my friends did was ask for information that was not on my FB profile. After that, the hacker went silent.
So, if something seems odd, ask questions, make folks prove what they say.
