Great news for serious hosts ...
We've only had bad experiences with guests from South Korea until now, here in Vietnam.
So often we've received uncomfortable or unclear requests, usually about "local girlfriends", meaning prostitutes, which we've always declined. The same when they don't answer to any of our questions.
But whenever we host them, we can't behave as we do with the rest of the world. They perceive everything differently, either because of language barrier or because of their habit to only interact with Koreans. We never feel comfortable.
They look very surprised to have to meet human beings before checking in, indeed. Probably because there are many hosts allowing self check-in to any guest and closing their eyes as long as they get paid ...
We've been treated very harshly once by a group of Koreans, and since then, we always have to insist on our House Rules, half of which we've added only for Korean guests, indeed, to protect us. We always redoubt wrondoings until they leave, because we don't live there so we can't check what's going on during theyr stay.
So now it's one more thing, special cancellation rules for Korean guests?
Why doesn't Airbnb protect more hosts instead of giving one specific category of guests even more leverage to worry their hosts.
Why should be feel guilty to be more worried with Korean guests?
