I just read the link you provided above. Thank you.
When I Googled airbnb retaliatory review it took me to a different page, which was less helpful.
From this page I am extrapolating from their one example that IF the Host has made a complaint or request for reimbursement for violation of House rule on the platform, and the Guest review is negative, that Airbnb will more likely remove that review as retaliatory.
I’m reluctant to say this but there’s also the ‘opportunity’ for a Host who feels that a bad review is coming, perhaps from a delinquency on the part of the Host, to make a complaint on the platform in anticipation of a negative review for which the Host can now seek removal based on retaliation. We’ve seen guests do this; Hosts, of course, can be bad actors as well. I suppose that this is nothing new as well.
It does seem like Airbnb is in a tough spot. Reviews are important to both Host and Guest, but much more so for the Host for whom this might be if not a living, at least business income. So Hosts are incentivized to invest energy in the process.
Evaluating a review as retaliatory requires judgment, which is a more expensive skill to hire and train for. Your comment that the pattern of Host reviews should be part of the process ( perhaps a central part) by which these judgments are made strikes me as a good one.
In my opinion Airbnb needs to think this through more carefully, especially for new Hosts. On the one hand new Hosts might well make mistakes resulting in negative reviews that can cost them dearly. On the other hand, a retaliatory review or just a review from a guest who doesn’t understand the system can unfairly hurt the new Host. Either way, that new Host seems to me to be a special case and one warranting some hands-on attention, including continued support after the setup as a new Host, per @Annet3176 (I hope I captured your sentiment accurately on the need for continued support).
I also like your idea of a Host being able to remove one review per year – no questions asked. Simple, fair, easy.
