The people behind an anonymous Instagram account that shook up the advertising industry with its attempts to take down alleged sexual harassers appear one step closer to being revealed.

Over a year ago, the advertising industry was fascinated and unnerved by the emergence of an anonymous Instagram account called "Diet Madison Avenue." The account aimed to expose sexual harassment and discrimination at ad agencies. It claimed it was run by a collective of 17 men and women working in the ad industry, with the help of more than 40 others. Its profile at one point included a link to whistleblowers' rights and the words: "Exposing sexual harassment & discrimination in ad agencies since Oct 2017, cuz HR won't. Stories researched & confidential."
