Actress Jameela Jamil has called for Instagram to ban posts and accounts that list and compare the weights of famous women.
The star of The Good Place shared a screenshot from a Selena Gomez fan account on Monday, which compared the alleged heights and weights of Gomez, Ariana Grande and Taylor Swift.
"What are we doing to our girls?" she wrote.
"Social media is great but so dangerous when ignorant MORONS give misinformation to women. Why do we want girls to agonise over this? Why is this what we write about three of the most successful powerhouse business women of our generation?
"I'm so sorry for all the girls who are currently sitting in their bedrooms, missing their lives, thinking that they need to match a certain weight to be worth something in our society.
"Instagram should ban these."
Jamil then linked to another Instagram account she runs, @i_weigh, which encourages girls to value themselves for more than their body type.
The "I weigh" movement asks users to submit photographs of themselves with captions describing the ways they are worthy other than their physical appearance.
Hundreds of photos are shared to the page, each with the words "I weigh:" followed by statements such as "my passion for art", "improving mental health", or "having supportive friends and family".
Each statement ends with the words: "F**king kg".
Since Jamil's post, hoards of her followers have taken to the Gomez fan page's photo asking for it to be taken down.
At the time of publishing, the photo had not been taken down and the page had since posted more of the same content, comparing the weights of celebrities.
