SO, I just got off the phone with two different helpline people on ABB, the first told me references were still a thing, and hosts were still able to require them as part of their requirements (which we have asked of new travelers for years)
I was not seeing the "request references" tab on the references section... and I called back again.
the second helpline person wasn't sure, and put me on hold to ask a supervisor. he was told the references are being phased out and will soon no longer be a thing. Existing references are in place, but no new users will be able to ask for them. THe request references tab has been removed, and soon so will all our personal references (which is not the same thing as a rental review).
HOSTS: if you go to booking settings under your listing, there is no longer an option to require a personal reference.
TRAVELLERS: if a host tells you you will be declined because you don't have a reference and asks you to get one, tell them they are discontinued and refer them to the ABB hotline to confirm the fact that they are being phased out. they will probably thank you for the info!
So far airbnb has not notified hosts to let them know this is being phased out, so I'm sure there are still tons of people who still have this as a rental requirement.
