I am on Instant Book, @Valerie283. And I noticed that some of my upcoming reservations, booked sometimes even in December, are of members with no face photo. I requested all the three of them to update their profiles, at the same time writing to the support to have an excuse to have airbnb cancel those reservations (just in case). Guess who was quicker with response? All the photos were there even before I got the reply from an airbnb rep. Airbnb doesn't enforce this rule (of having a clear photo), but if a host questions a reservation in such a case, there is no excuse for the guest. So you know what - let us hosts unite in this pursuit. 😉
