I don't mind professional listings, really; but I do mind fraudulent ones. And AirBNB isn't setup to encourage honest feedback.
My singular experience with AirBNB was a listing where they advertised a NYC address 2 avenues from the real address; they lied about details; they used a multitude of names; they told me to lie about who I was to a superintendent who might stop by. The place was a pit.
But my recourse was limited, because I didn't feel like getting into a fight with fraudsters who knew my real identity but who'd hid their own, and AirBNB doesn't give a shit. So I just recognized that AirBNB is a haven for crime, realized that their review policies are designed to protect the criminals, and I stopped using it, and became an anti-airbnb advocate.
I hope I meet Brian Chesky someday, because PG loves to go on about what a great guy he is, but as near as I can tell he's a sociopathic asshole who made purposeful design decisions specifically to enable fraud that happens to increase his profits. This makes sense, given that he built the whole damned thing by being a spammer (and lying about it). I'm genuinely curious if he's not the completely worthless piece of shit that he absolutely appears to be from a customer standpoint.
