My antipathy towards AirBNB comes because my experiments using AirBNB exposed me to:

- hosts using fake names - hosts using fake addresses - hosts giving deeply inaccurate descriptions - hosts telling me that the super might swing by, and I should introduce myself as (some other name) friend of (another name I'd never heard) if I ran into him. - neighbors of the unit giving me the stink eye, presumably because of what other guests had done.

My personal experience leads me to believe that AirBNB is, at it's heart, a platform that is built to create negative externalities. The processes in place to correct these issues are non-existent, which indicates to me that AirBNB knows this, and does not care.
