A chat app where South Koreans can anonymously dish the dirt on their misbehaving bosses and colleagues is belatedly stirring the country's Me Too movement, shedding new light on sexual harassment in the heavily male-dominated corporate culture.

Prompted by a recent wave of complaints about workplace misconduct — including a groping allegation made by a South Korean public prosecutor last month — the app Blind has added a new feature: a message board dedicated to a rising number of stories of harassment.

"We thought the prosecutor going public would put fresh momentum in the Me Too movement in South Korea, and our Me Too board was definitely inspired by her action," Kim Sung-kyum, co-founder at Blind's creator TeamBlind said.
