A representative from Instagram said that the earliest post the company could surface for this current cycle of the challenge was posted a week and a half ago by the Brazilian journalist Ana Paula Padrão. Others have noted that women in Turkey began sharing black-and-white photos recently to raise awareness about femicide. Though the portraits have spread widely, the posts themselves say very little. Like the black square, which became a symbol of solidarity with Black people but asked very little of those who shared it, the black-and-white selfie allows users to feel as if they’re taking a stand while saying almost nothing. Influencers and celebrities love these types of “challenges” because they don’t require actual advocacy, which might alienate certain factions of their fan base.
