I received a FB messenger notification that someone I am not Facebook friends with added me as a messenger contact. How is this possible?
Oh, I didn't know that was possible. But is it safe to accept messages from someone I don't know at all?
It really depends on the situation. If you don't know the person and are uncertain about their intentions, it may be best to ignore the message. You can always block and report them if they become harassing or inappropriate.
