@Patrick2086 I don't think it's that Airbnb is losing control of that, it's that they turn a blind eye to complaints about hosts and listings that bring in tons of revenue. $ is king.
There have been many cases of unscrupulous hosts that do bait and switch, and poor management, and have dirty listings in bad repair, but those listings aren't removed because they manage hundreds or even thousands of listings and fill Airbnb coffers with guest service fees. Some have as low as 3* ratings.
Some of us have been entreating Airbnb to separate these property managed listings from owner or co-hosted properties, so at least guests can tell at a glance what they are dealing with. But like everything else, falls on deaf ears.
