I was a host on airbnb for 2.5 years. I had a perfect profile - some people who checked out many other hosts told me i was one of the best on the site.
I started noticing an very disrespectful attitude Airbnb had toward me (and I'm sure everybody else), for example: I had the most strictest ban on smoking in my apartment (in new york city apartments are small, and smoking inside is just impossible), but one guest smoked anyway, Instead of evicting him without any refunds as i promised in my house rules, i let him stay and then claimed his security deposit.To my complete shock, Airbnb denied me! The guest admitted to smoking (in airbnb email system), I had pictures of cigarette butts in the trash, house rules were always there - both before and after the guest booked - they still denied me the deposit! I filed a complaint with BBB.org.
Guess what Airbnb does next? THEY CLOSED MY ACCOUNT! DEACTIVATED MY LISTINGS!

An update: I contacted SF DA's office, and they made Airbnbn refund me ALL the money I claimed.
