Black travelers share how they are discriminated by Airbnb staff

Airbnb prides itself on offering more than accommodation. The short-term rental platform refers to the hosts and guests that rent out and stay in homes around the world as a "community." But a community is rarely without problems.
On Friday, NPR hosted a Twitter chat with the hashtag #AirbnbWhileBlack. Airbnb's service — which includes the photos and names of travelers looking for accommodation — has been in the spotlight because of alleged discrimination by hosts against non-white guests. 


Airbnb lists its anti-discrimination policy on its website, stating the company prohibits "content that promotes discrimination, bigotry, racism, hatred, harassment or harm against any individual or group, and we require all users to comply with local laws and regulations."
But while the service can enforce rules against what listings say, enforcing non-discrimination is more complicated: A host could have nothing discriminatory in their listing but refuse booking requests from travelers they either consciously or subconsciously have a bias against.
 When will discrimination against the black community stop?
