This would probably be the most practical way of dealing with issues like this. A tag such as "[Unreliable] Host canceled prior availability dates 5 or more times." would make these assholes think several times before canceling on someone because of their skin color.

I also like the idea of showing someone's profile photo only after they book. Really, there is no reason for anyone to see my photos for short-term rentals.

Maybe the two could be tied together! That is, if I start canceling prior availability dates more than a couple times, AirBNB will stop showing me profile pictures of prospective tenants in advance.
