@Shaun69 There is a major flaw in the way Airbnb allows people to set up their accounts, in my opinion: once the account is set up and ID is verified, guest can change their picutres and names to anything they want. Because we don't get an actual copy of the ID, we have no way to verify that the name on the profile even matches the name on the ID they provided. It's the same with selfies: they can add it, have it verified, then delete it.
I saw one recently that said that their ID was verified and selfie checked, but their name was HappyLuck Cat or something equally inane and the profile pic was of, presumably, said moggy. Surely no one is issuing driver's licences to felines, and yet, there the profile stood.
If you're concerned about the lack of picture, I would ask them to add one to their profile.
