Yep, and don't forget that savvy hosts have ways to prevent you from leaving a review (I don't know how, but I do know that when we had to leave a cockroach-infested unit, we were unable to leave a review). That means that there may be people who want to leave an informative (and bad) review, but are unable to do so.
I did notice that the last review I left isn't actually displayed on the site. It was far from negative, but I did leave 4 stars and note the extraordinary thinness of the walls, as it made hanging out inside of the apartment a bit of a exercise in stealth. Strangely, review was never listed.
We left a unit due to numerous undisclosed defects (effectively no hot water in shower, cockroaches) and moved into another Airbnb. We were not allowed to leave a review for the problem unit. It was as if we had never stayed there.
Has to agree to what? I thought reviews were between the reviewer (host/guest) and the platform, and that the reviewed party can only see it after they submit their own review.
In my case, there was not even a chance to write a review, not that I wrote a review and it didn't appear anywhere.
It seems that Airbnb's policy effectively hides the worst reviews (ones where the guest is moved to another unit and the host terminates the stay in a way that prevents a review from being possible), which contributes to the 'grade inflation' that we see in Airbnb ratings.
That's not at all the same as what was claimed in this thread that hosts can prevent a review from appearing in the first place and that hosts have to allow the review before it's published.
