Unlike others here I wouldn’t waste my time calling customer service. The CSR is unlikely to know or care. If everyone whose search ranking changed called in people with real issues would never be able to get though.
I absolutely think, but have no evidence to support the idea, that having a claim downgrades you in ranking. I also board dogs in my home and participate in online groups with my fellow hosts. Hosts who have a problem like a lost dog, dog fight, sick dog, cancel a booking due to an emergency found themselves dropped in search rank.
I think we’ve discussed it previously on this forum. From a business perspective it makes sense. While they determine what has happened they drop your ranking so they aren’t dealing with issues on top of issues. I’m not saying you are in any way to blame, I’m simply saying that from Airbnb’s point of view, it makes sense. It’s no different than us declining a guest who has iffy reviews or who has left them for other other hosts.
If it was discussed before it would probably be in more general threads about the search algorithim.
