This strikes me as naturally similar to many human marketplaces, such as craigslist roommates, hiring practices, where to go grab a drink -- which have long been reflective of similar biases. In my anecdotal experience, the scales on airbnb/couchsurf/craigslist roommates/similar are even further tipped in a sexist? manner, dramatically favoring females.

There is little surprising or special about the sharing economy resonating these patterns. However, It does provide an excellent venue for study and potentially creative mitigation.
