Hi there, I am noob, Recently received PM on facebook from a stranger with quite of the blackmail information about my GF. Apparently the dude was in her friends list. I approached him, interrogated him, checked his mobile, his laptop - couldn't find any proof that info was sent from him. As far as I know bug with facebook emails is not working anymore, isn't it? If so, is there another method (description not needed) to write such message? As info was personal, person should be in close group of friends, so maybe there is a method to check who is blackmailing me? If I am asking wrong place, wrong people - where is the right one?
