A racist Airbnb host has been ordered to pay a 5,000-dollar fine and take a college-level course in Asian-American studies after she canceled reservation because the guest is Asian, The Guardian reported.

In February, Dyne Suh, a 26-year-old law clerk, drove with friends to a mountain cabin in Big Bear, California which she had booked via Airbnb. But after hours of trip in rain and snow, she received text messages from the host, Tami Barker, canceling her reservation.

The texts read: "I wouldn't rent it to u if u were the last person on earth" and "One word says it all. Asian."

The host also said: "It's why we have Trump ... and I will not allow this country to be told what to do by foreigners," according to The Guardian.

Suh, who is an American citizen though it was hardly relevant in the case, recounted the experience in a YouTube video posted in April.

"It stings that after living in the U.S. for over 23 years this is what happens. No matter if I follow the law... no matter how well treat others, it doesn't matter. If you are Asian, you're less than human and people can treat you like trash," Suh, who worked as a law clerk at the Riverside County Public Defense's Office, said in the video.

After Suh filed her complains to Airbnb, the accommodation sharing service provider carried out its own investigation and banned Barker from the platform.

Suh also complained to the California department of fair employment and housing (DFEH), which ordered Barker to make a personal apology to Suh, pay a 5,000-dollar fine and take a college-level course in Asian American studies.

Airbnb, which is headquartered in San Francisco, reached agreement with the DFEH in April which allows the regulator to test and penalize Airbnb hosts for racial bias. Barker is the first Airbnb host that has been punished under the agreement.

Airbnb gave in to the DFEH's demand after researches and a growing number of reports suggested hosts regularly refuse guests due to their race, a problem exposed in 2016 under the hashtag #AirbnbWhileBlack.
