Re: To be fair to AirBnB I don't think they can be held responsible for people doing this
"Probably because there's no way they can really know. In this example"
The whole problem with their business model is that they're taking money for something for which they should take responsibility which they find difficult to do. Their response to the Irish incident suggests they expected to get away with doing nothing.
It's their problem and we should hold them responsible for solving it. If they can't or won't then their entire business deserves to go down the tubes for being built on an unsustainable model.
