If you want to protect your identity DO NOT book with Airbnb. Their policy (that airbnb does not have the courtesy to disclose upfront but only when you pay after spending hours researching your vacation accommodation options) of requiring offline AND online identification is crazy. For offline verification, US clients must give last 4 of SSN and birth date or passport or drivers license uploaded to airbnb's site PLUS they also want online verification - a link to your twitter, linkedin or facebook! And if you can't supply that then a uploaded video of yourself to airbnb's site! I do not give this info to the IRS or my bank AND they do not request it either. Airbnb certainly is not my personal friend and they now have access to nearly ALL my life both financial and social! In this day and age of ID theft, crazy! Bye-bye Airbnb. I'll be back if you revise your new policy.
