Private hosting via a platform like Airbnb, oftentimes requires a certain set of 'survival' personal skills, and does require handling, on the spot, of every day small conflicts with particular people. Otherwise, any situation will become a stretched, time-wasting endless unnecessary conflict.
And especially with Airbnb in particular who judging by the mentality of the founders which I gather is wanting to establish a whole new world order of everyone ultimately loving each other. The mere introduction of the word 'uncomfortable' for example is a giant leap in itself, because is so subjective and personal.
In my 'younger' days, things were 'simpler', women would tell this creep to drop dead and do not text them again with such nonsense. In the home sharing reality however, there is the potential 'hostage' situation with the Review, which yes changes the whole dynamics and harnesses personal freedoms of expression by the host.
I think what is really missing is Airbnb being just as tough with guests than they are now being with hosts, namely they do need to back the hosts more, and this will make the host's job easier to handle such situations like Claire's by her and on the spot and feel confident about it, and then not having to get Airbnb involved with it.
Disclaimer: In my 'younger' days we really didn't have texting per se, but used two cans with a tight string between them to communicate from cave to cave. And yes, the women also carried a big club!
