I knew there were quite a lot o complains about the fake profile pictures, either intentional or unintentional one.
Here is my experience:
1. An Asian guest booked a room in a flat which was supposed to be girls only (as stated on the Ad, there is no option to restrict male/female guest on AIrbnb). It was difficult to tell from his/her name. But the profile picture was a girl. When he turns up, it freak me out.
2. There was middle east another football friend coming for a match, whose profile was an European. I was very surprised when he turned up. At least that time was a guy but it's a different person showing on the profile.
3. There was another girl booking with a profile picture of cats...
As a host, I tried to be honest to Airbnb and my guest.
Airbnb, can you do more? Profile picture and ID check is the first line of defense for the host safety.
