I have about 10 'friend requests' sitting in my inbox from people I don't know. Not only don't I know them, but we have no friends in common. Most have one or two photos. Most have almost no activity on their profiles. Most I can't even tell where they are from. Who are these people? I could see if we had friends in common that someone accidentally may have pressed a button on a phone, or something, but these are completely random.
