I turned it off several months ago. I think around May '22. I don't remember now being spammed by Airbnb but, if I was, it must have stopped after a while.
What I do remember was they didn't make it easy for the third listing. I disabled IB on two without too many problems, and just ignored all the prompts during that process asking me if I was really sure and extolling all the benefits of IB. However, when I went to disable it on the third listing, there were many more prompts and stages. A few days later, I realised that it had somehow been magically reactivated on that listing...
