Could Cardano help a real estate website avoid fraudulent listings?

Hi. I am looking for ideas to avoid fraudulent listings with more emphasis on vacation rentals.

Any idea?

Thank you.

How does the fraud work?

A common fraud in this sector happens when the customer of the vacational rental arrives to the destination and discover that there is no home and host. Some few people list ad using photos from other sites and ask money for reservation.

I know that an app using smarts contrats can prevent from losing money in a way requering the both parties agree to the transaction; but I would like ensure that the rental ad is a genuine offering from the begining.

I would like to avoid the use of ranking the ad or host because it can be manipulated. Even when the ad is genuine can be manipulated by competitors.
