You may insist on this though ABB appears to not care. My house rules say that a profile must be complete (photo, narrative & Govt ID verified) so when a flower pot IBs my house (happened this week), I just message and remind them that they'll need to upload a proper picture. Also, my rules say that they will be sending me a copy of their ID, along with their rental contract and that I may verify all guest IDs at arrival. Bc regardless of what photo they upload that is not at all an indication of who they really are.
Hosts, you can ask for more verification than ABB gives you. The info they pass along is an introduction, nothing more
