I personally will not send anyone any face picks. Nor will I FaceTime, or point to my LinkedIn, or show pay stubs.
I could take a picture of my ID, block-out all vital information and only show my face and partial name. As a provider, I can use this information, to find this person, in case if he hurt me. For my security only.
Walk a mile in other's shoes, to understand their behavior. What would you ask if you are a provider, who is about to invite a stranger in your house? What will scare you? What will make you relaxed and eager?!
