These people post fb message from one of your friends, using their fb pictures. As how you are etc, then say that they won some money and tell you what they did to get it.They really pretend to be your friend, in my case a friend I have had for 50 years.Then is when the arrasing begins when you realize it is a hoax. I got a total of 10 nasty messages, and then they started with messaging my cell, with same nasty messages after I wouldn't send money to them. My friend then posted she had been hacked.
