@Sybe I am afraid I just tried to remove what I consider to be a 'retaliatory review' left some months ago, and just contacted 'support'. I offered to share supporting info. in my initial contact.
Unfortunately, I was confronted with the usual ridiculous 'support' agent reaction. They 'reviewed' the info on the platform, and came back with the standard scripted response about reviews, etc. and concluded the review cannot be removed. This is WITHOUT asking me for ANY supporting information. And yet the announcement bulletin clearly states..." When you dispute a review, we’ll ask you to provide evidence, such as photos or message threads with guests.... " NOT ALL communication is on the platform, especially when a guest is staying in a shared home with the host, for example, or where the communication has been verbally by telephone, etc. And what exactly constitutes a 'serious' violation?
In my case, I found out other 'superhosts' have made similar remarks about the same guest, who failed to communicate, and has not read the listing and rules, and then makes some exaggerated and false statements or some dissatisfaction AFTER their stay!
As usual, I believe the airbnb platform is unfair to Hosts, let alone 'Superhosts'. Support is as ever disappointing and tortuous, and sadly a waste of time. I have even had invitations to 'review' a recent support agent, and found that the name of the support agent I was being asked to review was not the same person that had corresponded with me at all! And I might add I only get asked to 'review' selectively, and not all interactions.
It is disconcerting that hosts take a chance with guests who have no experience or reviews with airbnb, and then to find the airbnb attitude towards experienced hosts is predominantly unfair. The 'superhost' status is merely there to help airbnb earn more revenue, and is worthless when it comes to credibility in the eyes of airbnb.
Not at all satisfied that these apparent 'new updates' have been thoroughly thought through, or may be properly enforced, implemented or executed.
