@Lisa934 Airbnb suggests but doesn't force guests to have photo of themselves. Also many hosts don't have photos from them but a logo or some sigh or a picture. We don't even see the photos until after they book so you have accepted the booking anyway and you can cancel it if you don't feel comfortable. I would suggest informing them that they will have to show an ID when they check in, in order for you to confirm their identity. The ones that don't feel comfortable can cancel up to 48h penalty free.
