Instagram recommends sexualized content to young teenagers within minutes of their first log in, according to studies from The Wall Street Journal and Northeastern computer-science professor Laura Edelson.

The studies, which consisted of scrolling through Instagram Reels using new test accounts with listed ages of 13, found that adult sex-content creators appeared in the test accounts’ feeds in as little as three minutes, according to The Wall Street Journal. Additionally, if a test account chose to skip other forms of content and watch sexually suggestive content to completion, its feed would be dominated by sexualized content in under 20 minutes.
