Do you think they will take your advise?
I don't think so.
I have many bad experiences with bad guest, gave bad review because of their fault, but Airbnb do nothing.
I send feedback, talk to supervisor, if the host and guest has the conflict, the review most likely is not fair to one or both.
so if the trip is cancelled, or shortened, or in the chatting system, has the conflict, the review should be cancelled for many times, but they still let the review there.
the bad word from guest, host has chance response, but the most hurt is the review star points, which now, if one all 6 - 1 star review, you need around 50 all 5-star review to balance it, if you still need get superhost, which need to get 4.8 point overall.
Too bad for superhost.
and I guess Airbnb just don't want do this, because if superhost like keep superhost, have lost from pocket, and thun Airbnb get less job to do for the customer services !
