Airbnb doesn't let the hosts check picture ID of the guests

[Kevin Lefeuvre]

I have been asking for photo ID, it's written in House Rules, listing, everywhere... and when they refuse, I let them cancel within 24 hours with no penalty.

In a recent case, the guest complained to Airbnb, who backed them and after a few back n forth, here's what Airbnb wrote to me:

The request for a copy of ID is something that you require from guests but is not supported by Airbnb and will not be enforced. It is a prohibited activity listed in Airbnb's Terms of Service. If you choose to uphold this requirement on your listing please note, that if you elect to refuse a guest entry because they did not provide a physical ID it will be your responsibility to cancel the reservation. In these cases, all cancellation penalties will apply and your calendar will remain blocked. The reservation with xxx is a one time courtesy where penalties will be waived as I have provided information of our Terms of Service.

Who else is requiring ID ? What are the challenges you face doing so?
