In an open letter to Facebook, Instagram, TikTok and Twitter, girls from around the world called on social media companies to create more effective ways to report abuse.
"We use (your platforms) not just to connect with friends, but to lead and create change. But they are not safe for us. We get harassed and abused on them. Every. Single. Day," they wrote.
"As this global pandemic moves our lives online, we are more at risk than ever."
Plan International also urged social media companies to do more to hold to account those behind online abuse, and to collect data on the scale of the problem. (Writer: Emma Batha, Thomson Reuters Foundation | Editor: Helen Popper)
