@Mathieu-And-Kunj0 @Rebecca160 and all: So I had to call Airbnb about another matter and happened to get an amazing rep. So I decided to ask her about the new rating system, who might get delisted, etc.
She said the following, as summarized here:
1) Hosts will NOT get delisted for falling below 4.7 without receiving many warnings first via email. If the emails are not responded to (including correcting whatever the issue is) the host may be delisted.
2) Hosts should always politely challenge any Airbnb rep that refuses to remove what is obviously a malicious, retaliatory reviews. This rep said she removes many of these herself. She said reviews are supposed to be relevant and not needlessly harmful and destructive to either host or guest. It would be wonderful if all reps were as knowledgeable, caring, and empowered as the rep I reached today - But, as we know, they are not, and several hosts here have lost their Super Host status over an undeserved and/or retaliatory review that a rep refused to remove. Maybe a training issue? If so, it would be great to see this addressed.
Here's one new concern I have, based on the above: I myself do not receive Airbnb emails except as related to my reservations. I receive no updates from the CC, no emails from Corporate, etc, and my notification settings are all correct. It is not going into Spam or anywhere else, I just don't receive it. In fact, the rep is going to kick this over to the tech team to try and resolve, as I have not received emails beyond the basics related to my reservations since signing up. If other hosts have this same issue, and/or the Airbnb emails warning them they may be delisted go into 'Spam' or 'All Mail' (which are the Social / Promotional email folders in Gmail that many people never look at) they might not ever know they were in trouble with the algorithm-driven Bot and next thing they know, they are delisted. Given this, I think it would be better to receive this kind of important information via the Airbnb message thread as well as by email.
On a related note: I have also been thinking more about why professionally property-managed listings might be delisted only if they consistently fall below 3.7 versus 4.7 (if what I was told by that one property manager I mentioned is true): In my neighborhood, I am one of a hand-full of non-property managed listings. In fact, I am the only person living full-time in my home in this one section of ocean-front houses I live in. The rest are ALL property managed vacation listings that are now starting to post all of their inventory on Airbnb.
It is clear from reading the reviews that I am scoring much higher in cleanliness and other areas than the property-managed listings. I am not sure how many property managed listings could 'consistently' maintain a 4.7 'overall' rating, based on my observations this past year as I keep an eye on the market. Busy, harried cleaning crews (which are in short supply around here in the high season) aren't going to put the same amount of love, care, and energy into preparing the home for guests as an owner/host (hopefully) does. And, based on various press releases I've been reading, Airbnb very much wants to cater to these vacation rental-type listings so as to go head-to-head with Expedia, etc. So it may very well be that property managers have a lower bar set for them than we 'regular' hosts do.
If any property managers are reading this, it would be great if you could confirm that your properties will remain listed unless they fall below a 3.7 as we still do not know if this is accurate information or not and I think you are served by different customer support than we regular hosts are.
