2. Airbnb did not block the host nor did it tell anyone about the host
3. The host tried to drug-rape his guests again
4. Japanese police found about 'white powder remains in the cup given by the host'
5. Airbnb's 1st reaction: he didn't intend to do it.
6. Airbnb's 2nd reaction: Japanese police said he's ok
7. Airbnb's 3rd reaction: We'll educate the host on the matters
8. Airbnb's 4th reaction: We'll do something about it (...but what?)
I chose HN because I saw some Airbnb founders/employees hanging around, and I'd expect them to solve these kind of issues. Maybe the Korean / Japanese Airbnb customer service is not doing their job/etc...?
