I know this is a high risk business and accept that fully, however I also ASSUMED Airbnb did background checks on new people signing up as guests, do they not?? You know that gut feeling you get, the bad one, after chatting with a new guest who's set off a dozen red flags? I had that feeling with my last guest who did ended up screwing me royally, but what really concerns me most is that I did a simple google search using this guests name and found an impressive criminal history of arrests for shoplifting, theft and drug (meth) charges. Going back about 3-4 years she's been arrested over a dozen times! The last was a week ago for theft! I truly am shocked that she's able to book and I'm also thankful that she took me for less than $500! My confidence in our company is shattered today. It's quite shocking that she's not in prison, I have no doubt that's where she's headed. Did you think airbnb screened and did background checks? I know, never assume!
