I'm curious how they enforce this. I've never used airbnb but what's to stop a host from reading the reviews from a guest account instead of their host one? I'm assuming they're still published publicly but maybe I'm wrong?
See my other reply in the thread, but basically, they were doing a lot of stuff that at first seemed like proactive customer service initially, but later seemed much more like scouting to determine if i was going to give them 5 stars or not.
