I only stay at Airbnb's that have at least some reviews. It doesn't take too long to determine if reviews are sock-puppet-generated or genuine. You have to actually stay at the property to write a review, which means paying for the stay since Airbnb process the payment. Obviously you can create wash transactions but the transaction fees would still be significant.

Another approach is to sent a question to the property manager. Invent some pretext to ask a question. I find that people trying to scam customers on the product also have poor customer service skills. So if I don't get a prompt, cogent and polite response, I move on..

You use common sense - I have been a host of properties and I would say Airbnb does not go to any lengths to encourage you to misrepresent. In fact they do the opposite - with your listing you are building a contract so they encourage you to be as specific as possible and accurately describe the guest experience and your expectations as much as possible. They also strictly govern guest interactions so you can’t provide a phone number or email address during negotiations to side step the system. Overall I think the people who are saying it’s a scam are amplifying a bad experience to suggest that it represents the whole system. It clearly doesn’t and I say that as having seen how it works both as a host and a user.

You roll the dice and hope for the best. There's only so much you can do. Pick 2, cost, comfort, reliability

> How do you corroborate the information on those properties? There is no way to corroborate. For most listings, Airbnb is the only source. However, I've never found this to be an issue. I don't believe I've ever been "scammed" by an Airbnb host in 40+ bookings.
