Yeah, credit card should be enough. Any unhappy employee or kid working at Air bnb could simply make copies of ID's to sell on the black market. I dont mind showing ID to the host, that is standard, but look how the Russian's hacked Yahoo and many defense databases, no way my ID is secure at an Air bnb database. Once you are a victim of ID theft, you will never be able to clean your record completely, even with an attorney. And any progress takes many many years of rebuilding. Is it worth it? Plus if Facebook buys Air bnb, then who owns my ID? I would give up my LICENSE PHOTO, and LICENSE NUMBER - but not my other stuff.
