Thank you for highlighting this issue @Susan0.
After a number of high profile people of colour, particularly in the US, publicly stating that they don't use Airbnb because they've experienced discrimination, I can understand the reason for Airbnb trying to remove this stigma prior to booking. What is less understandable is that they do not require a photo at all. I imagine that the burden of verifying the photo with the Government ID outweighs the tagline about the community being based on trust.
I have to see ID as a requirement from the Municipality, so I always check the name matches that on the booking, which helps. Although only this morning I got told by on CS rep that they are not pushing the third party booking restrictions, and that such bookings are at hosts' discretion. Which maybe so, until such time as a claim against the Host guarantee is required. It seems in general , Airbnb is finding its own policies too irksome to implement.
Yet again, it seems the burden of checks and balances fall squarely on us hosts. I will personally have no qualms on letting guests know I require a photo, after the booking is confirmed. I hope other hosts insist on the same.
