I think BnB shouldn't make it mandatory for some new hosts to use Instant Book. This has led to new hosts having to take on unsuitable, guests or being penalised because they don't understand the system and cancel guests who aren't a good match. It has also led to concern from existing hosts that it will be made mandatory for all hosts.
It isn't a good introduction for new hosts to being on BnB. There are numerous complaints on the other forums and social media.
I have contacted BnB via social media and the other forums to try and understand why it is doing this and get a response on behalf of new and existing hosts. However BnB refuses to answer and just says it will pass my comments on (to who?) or that new hosts can use house rules to filter.
It never answers the simple question - why have you introduced manadatory Instant Booking for new hosts and will you allow hosts who are uncomfortable with this to turn it off?
As we know no house rules can cover all bases and it is often when communicating with a guest that you understand whether they are a good match.
Response from Airbnb
Instant Book is not mandatory for any host - although we encourage hosts to give Instant Book a shot.
If you do decide to turn on Instant Book, there are safeguards in place to help make sure that you’re only accepting bookings from suitable guests. You can choose to only accept Instant Book from guests who have been recommended by other hosts, you can require Instant Book to accept guests who have government-issued ID, and all Instant Book guests must agree to your House Rules. Plus, you can cancel Instant Book reservations immediately without penalty of any kind, if you feel uncomfortable with our guest or with someone who breaks your house rules.
Many hosts find that they get up to two times the reservations when they turn on Instant Book.
