Ladies, what is the point of these silly requests: "call me first" "FaceTime me" etc. It doesn't guarantee your safety at all and all it does is de-anonymise both of you. The dude could still be a psycho nut job even if he speaks nicely on the phone. He could still be Leo even if he goes through these hoops. It's literally completely pointless.
Also men, do not jump through these silly hoops that can screw you over in so many different ways. Let them find another job. There are more than enough that don't require this nonsense
