Instagram has been named the worst social network for cyberbullying, with 42% of all young people who have been bullied online claiming that it happened on Instagram.
In a survey of over 10,020 young Brits between the ages of 12 and 20 by anti-bullying charity Ditch the Label, one in three said they are scared they could be bullied online, and 69% admitted to doing something abusive towards another person online.
Of those who have been cyberbullied, 41% have gone on to develop social anxiety.
Although Instagram was found to be the most commonly used network for cyberbullying, 37% of victims surveyed said they were targeted through Facebook and 31% through Snapchat.
"Cyberbullying continues to be one of the biggest challenges facing young people," saud Liam Hackett, chief executive of Ditch the Label.
"Not only is the Internet redefining the climate of bullying, but also it is having clear impacts upon the identity, behaviours and personality of its young users."
Of those surveyed, seven out of 10 said they didn't think social networks do enough to combat bullying.
Anne Longfield, the Children’s Commissioner for England, said that social media giants have an important role to play to ensure children have the power, the information and the resilience they need in today's digital world.
"We need to understand why children are bullying others and to do more to combat the cyberbullying that is blighting many children's lives," she said.
"So I am calling for the big internet companies to simplify their terms and conditions so that children are aware of what they are signing up to."
Longfield also called on the Government to introduce a digital ombudsman to act as a mediator between the firms and children when there are problems, and for schools to introduce compulsory digital citizenship classes in schools so that kids are aware of their rights and responsibilities.
The news comes after a report by the Education Policy Institute last month claimed that it was "futile" to attempt to protect children and young people from all online risks.
Rather than monitoring or trying to stop the use of social media, young people need to be made more "resilient” to the dangers it poses, according to the report.
"Online activity is increasingly private. The rise of instant messaging means that online discussions are now often held in private groups, rather than on public profiles," it stated.
"The focus of public policy should be on how to develop resilience in young people to maintain their emotional and mental well-being and to live safe digital lives."
