Thanks for sharing, @Sarah977 ,
I personally don't see how paying will solve the issue, as anyone can pay an amount of money. It wouldn't - in my mind - "verify" anything other than the person's willingness to pay X amount of money to either continue with honest hosting or to continue fraudulent behaviour.
And the party house wasn't the host's error, it was the guests who rented a house saying it was for their family and friends, then using it for a party. Will Airbnb also start validating guests through payments, or what's the plan?
We're all hosted guests who turned out to not be who we thought they presented themselves to be, or invited additional people or in other ways mirepresented their usage of our house. How will guests be verified, especially since we don't see last name or picture before we agree to host them?
