Online abuse is driving girls to quit social media platforms including Facebook, Instagram and Twitter, with nearly 60 percent experiencing harassment and bullying. A new global study by girls’ equality group Plan International has revealed that one in five girls and young women has abandoned or cut down her use of a social media platform after being targeted, with some saying harassment started when they were as young as eight years old. Attacks were most common on Facebook, where 39 percent of girls polled said they had been harassed, followed by Instagram, WhatsApp, Snapchat, Twitter, and TikTok.
