Diet Madison Avenue has grown from about 800 followers at the beginning of the year to more than 18,000 as of last week. Recently, the group has been expanding its Instagram posts to include a wide range of equality and human rights topics, such as diversity and gun control. Last month, the group announced that several of its founders would reveal themselves soon as part of its plan to form a 501c3 and 501c4 organization.
