I, too, am currently in Instant Book Jail for cancelling a third party booking. I received the same comments from Customer Service (after a full week of back and forth), in that although the system shows this cancellation as "Cancelled by Admin" the penalty is system generated and cannot be changed. The advice given to me was as follows (this is a cut and paste of our conversation):
"Unfortunately, I don't have a link for the guidelines (Note: in an earlier conversation with this CS rep, she had said that this was a "guideline", which I quite reasonably asked to be provided with). The system looks at your overall listing activity, including denied bookings, cancellations by host, and other listing activity such as calendar views and reviews. If there are activities in a short timeframe that it considers higher-risk, a host may be temporarily switched to Request to Book. And while re-assessments are done every 7 days by the system, there is no set timeframe for being converted back to Instant Book. Being active within the listing, such as booking reservations and responding to requests, is what will trigger the system to switch you back to Instant Book. This is the extent of the information we have regarding the conversion experiment."
This began on January 22nd for me, and I have (presumably) now passed 3 "7 day review periods", but am still in the penalty box (Request to Book). I've had 2 guests cancel their bookings this week. Unsure if this means that I'm still considered "high risk" and will continue to be penalized.
Very frustrating and demoralizing to be penalized for upholding Airbnb's Terms of Service. As a relatively new host, I am still struggling with whether I wish to continue a relationship with this company.
