p.s. I still get guests who have "avatar" images up for themselves, rather than a photo of themselves. Because I'm a single woman, that is not okay with me, even if the guest is a woman. I require all of my guests to have a true photo of themselves, and a true full name on their account. People fudge with this all the tiime, but if I am uncomfortable, as a former criminal litigation paralegal, I can usually find out who someone is.... usually, and if I find the information a guest has provided on the Airbnb site does not match with what I can find online, I'll gently inform my guest, or, if I'm anxious enough call Airbnb.... my safety, and the safety of my other guests in my home, is paramount.
I believe Airbnb has been doing a fantastic job of creating parameters for safety, and overall I'm still as delighted with Airbnb as I was when I started working with them 7 years ago.
However, one does have to get used to the fact that they change their system about every 5 months, as they adjust to new technology. So, one is always on a learning curve with their application.
Consider it a constant mystery unfolding, and you'll be happier.
