Facebook has repeatedly found that its Instagram app is harmful to a number of teenagers, according to a Wall Street Journal report published Tuesday, citing Facebook studies over the past 3 years that examined how Instagram affects its young user base, with teenage girls being most notably harmed. One internal Facebook presentation said that among teens who reported suicidal thoughts, 13% of British users and 6% of American users traced the issue to Instagram.“32% of teen girls said that when they felt bad about their bodies, Instagram made them feel worse,” the researchers reportedly wrote. Facebook also reportedly found that 14% of boys in the U.S. said Instagram made them feel worse about themselves."
