I was contacted by Kingston Kim Marie who says she is a Facebook claims agent and I have won $500,000.00 in winnings.Is this true?

face book is a social media operation and does not give prizes
you can always call face book direct on the contact number listed at the bottom of the face book page ( not the one she gave you)
Be extremely wary of this as I am thinking big scam especially if they want your bank details to put the winnings into your account
I would dismiss it as a scam

Scam! You should never need to pay money to win money. http://scam-detector.com/social-networking-scams/facebook-lottery-chat

Did you enter a lottery?

No this can not be trusted, you can and anybody else on face book could make that same claim.

Hi:
This is a scam. Do not reply to it. If you reply, they will ask for your banking info to "deposit " your prize , or credit card info, and you will get your account cleaned out! Congrats for not responding to them immediately!

Beware! Its a scam. Do NOT give out any personal information. If you do, they (the senders) will probably ask you to deposit a small fee so they can send you the prize money. After receiving your cash they will move away!
Just send this email to your spam folder.
Just for your information, I also received one of these.
Thank you.
