If AirBNB wanted to quantify the risk of porn shoots, then they are in the best position for that kind of empiricism. The rest of us are speculating from very weak intuitions; just a bunch of posturing.
I'm well aware that sex can be messy, and I still maintain that professional pornographic shoots are far worse.
It sounds reasonable to compare the two, unless you've ever been on the set of a professional pornographic shoot.
Plus there tend to be additional people on set besides the actors, having takeout food, smoke breaks, etc.
Sure, it is all 'dancing' but the quantity of people has a qualitative effect on behavior.
This happens, a lot. Guess what happens afterwards? The hotel generally charges you a cleaning fee. (Which includes much more than just cleaning, but the days the room wasn't in an usable state etc.)
AirBnB also has an option that enables you to set up a cleaning fee to be charged if necessary.
Not just a "cleaning fee."
I've been in a plenty of hotel rooms that suffered far worse damage than I could ever imagine a porn shoot causing. At least I've never watched any porn that involved throwing things through the window, setting the carpet on fire and the entire building reeking of weed.
So, doesn't literally hold the world record.
Without getting too graphic, there's a HUGE difference between people having sex for fun and a professional porn shoot.
The latter is messy, smelly, and causes a surprising amount of lasting damage. There's a reason that so many porn studios film in hotels (and likewise, a reason that so many hotels refuse to rent rooms to people that they suspect will be filming there).
I won't go into details on HN because it's not really the venue, but let's just say this: if you knew what being "on site" at a porn shoot really looked, sounded, and smelled like, you'd never want to watch porn again[0].
(And we're not talking about an amateur porn shoot where people just film their "normal" sex on a webcam, either - Michael Lucas literally holds the world record for the most expensive gay porn film ever made[1]).
