Rejection, rejection and more rejection. That's what black users say they are experiencing on Airbnb.The vacation rental site is facing a storm of criticism from black users who claim that hosts are rejecting bookings because of their race. Their frustrations have sparked a hashtag -- #AirbnbWhileBlack -- that is a trending topic on social media. There, users are sharing experiences of being denied bookings for available rooms and homes. "My friends and are all well-educated, paid, etc.," said one user. "But I'm getting denied solely bc of my name/how I look. That's hard." Jamelle Bouie, the chief political correspondent at Slate, said that despite having good reviews on Airbnb, he is approved for only 25% of attempted bookings on the platform. "For cities we visit frequently, I end up staying with the same host, which has streamlined things considerably," Bouie said on Twitter.
