If you are uploading your passport photo online with all the info on it as is you are MAD!
I will not use airbnb ever until this requirement is removed.
Airbnb have my phone number, email and credit card.
Also, hosts can ask to see ID on arrival as well as rate the guests.
That surely is enough as it was until now.
I suspect foul play on behalf of airbnb, and fell they ask this for other reasons.
like targeting, selling private data and so on, which is why I am even more hesitant about airbnb now.
Hosts who don't see this as a problem are only hurting them selfs at the end.
Shame, but bye bye airbnb...
