Reporting the fake profile does nothing either. One of my best friends (life long) FB was taken over. Different name but it was her page. It took me a month to figure out what had happened. My friend died in 2012. A new name was on my friend's list (several months ago) but I really didn't pay much attention. I figured it was someone I was in school with. In Memories one day things came up from this person but the posts were the exact same things my deceased friend would say. Even an old nickname that nobody knew but us. Then the light bulb went off and I went to my friend's page. Her sister contacted me because she was getting the same. We reported it and FB came back with it didn't violate their standards or something to that effect. So we contacted everyone on our mutual friend list what happened. We have a lot of people from the old neighborhood growing up and from school.
Another faked account they messaged me asking to borrow money. I knew it wasn't the real person because they would never do that. I knew she had been hacked or whatever by the stuff that was posting. The killer was this person was trying to prove to me it was really my "friend". They sent me a copy of her DRIVER'S LICENSE! How they got a copy of her license I'll never know. I told this person "Since you live down the street, walk on over and get the money". No response. Later that morning, I sent a message saying I'm still waiting on you, when are you coming?
