My IB is off @Till-and-Jutta0 . I tried it once. Ended up having an IB from a person with two big dogs. I don't allow pets... Was a nightmare fixing an issue not made by me with all the threats of sanctions and punishments.
I have no problems understanding that guests would like to trust their host. But my risk as a homeowner is higher. Both financial, physical and emotional. So this passport should go both ways if they want it. Also, a passport is meant to give entry. So posting it on hosts who are the ones who grant entry can only be an idea from someone who doesn't know what a passport is.
Also, the ton of information they ask for is a huge invasion of privacy to be left on open profiles. They already have pictures of my home for everyone to see.
Of course we communicate. I couldn't be homesharing the way I do if I didn't. And I don't like asking potential guests questions like I'm interogating them. That will put them off. I have to keep my trust in people to keep hosting.
