I think this is long past due. For some background. http://www.nytimes.com/2016/08/23/opinion/how-airbnb-can-fig...
At the end of the day, despite the BS line that AirBnB gives about people sharing their homes, the majority of the hosts are operating a small business, and one that's beholden to a single provider for business. There will be hosts that lose 100% of their income stream because of this and not all of them will be the problem hosts that are causing this controversy. Innocent hosts who just happen to have accidentally chosen incorrectly a few times will get caught. Or, more likely, hosts will live in fear of being accused and start discriminating in favor of minorities.
