Has someone forged you username and done things you would never do!? Well I have the solution! With every post you make add a picture of your living room. But the forger could copy the picture so every time take a picture at a different angle so none of the pictures are the same but there of the same living room. So i f you post a picture of you living room and the forger copies it the first you that posted the picture is the real you but you need to change that angle of the picture for each post or it won't work. (for nobi)
