Remember, there is no Facebook lottery and once you are asked to send money, gift cards or other forms of payment in order to receive a so-called lottery prize, it is a SCAM.
This is How the Scam Works
Today, I received a friend's request from Mary Jerkins, Kansas City, Kansas. When I accepted, she proceeded to tell me I had won the Facebook Lottery. She showed me pictures of other winners. Then had a Mr. Martins contact me from 1-646-598-4273 to give me details on how to collect my winnings. I was to buy an ITUNES gift card, scratch off the back, send them a picture of it, and they would send my winnings on an ATM card within the next 5 hours. Upon further questioning they just told me if I didn't want to claim my winnings that were up to me that he (Mr. Martins) had more winners to notify.
