The most annoying dark pattern for me was not being able to give 0 stars for something and then averaging across completely dissimilar topics so that it was impossible for most hotels to score less than about 2 out of 5. So the location was great, 5 out of 5 but that doesn't make up for the terrible service and the noise 0 out of 5. Another thing that got me was the window dressing. They show the nicest room of the hotel on the site but the room you get when you arrive is nasty. Booking.com were famous for this kind of stuff and probably helped AirBnB get to where they are.
