I got the same Tracy message. My profile pic is of Muppets characters. I don't have my cell # on FB for people to contact me, so that was the first red flags. Don't reply to this message. If it was a real person on FB, they could just write you a message on the site.
I got this message a few minutes ago. I googled the area code 647. I did know a girl named tracy in ontario 4 years ago. Thought it was her. It was not her. Haven' used my facebook page in 5 months. Time to delete it.
