With more children and young people spending time online, cyberbullying is the top concern for their safety when using the internet, according to a survey carried about by the International Telecommunication Union (ITU) on two social media platforms. In the lead-up to Safer Internet Day this Tuesday, 8 February, the UN agency polled its followers on Twitter and LinkedIn to find out what worries them most about children being active online. They were asked to rank three common online fears: cyberbullying, data protection lapses, and the threat of grooming, which refers to abusers deliberately exploiting children online. Roughly 40 percent listed cyberbullying as the chief concern, with the two other choices at 27 percent and 26 percent respectively. Respondents also cited other fears that were not featured in the poll, such as the risk of excessive screentime, or whether children are aware of mechanisms for reporting online threats. That cyberbullying emerged as the top concern is hardly surprising, considering how the internet permeates nearly every facet of life. Young people spend more time online than the rest of the population, ITU said. an estimated 71 percent of people aged 15 to 24 using the Internet, compared to just 57 percent for all other age groups. The Internet has also evolved over time, giving rise to the emergence of new threats, making the protection of children and youth online ever more critical. ITU recalled that the problem of cyberbullying inspired Gitanjali Rao, TIME magazine's first-ever Kid of the Year, to use technology to tackle the issue. Ms. Rao, now 16, conceptualized Kindly, an open-source API (application programming interface) that uses machine learning algorithms to detect "toxic" language in text messages, emails, or social media posts before they are sent. Speaking to UN News last November, she described it as like "the spellcheck of bullying." Children receive instantaneous feedback on their draft messages, thus allowing them to reconsider or modify what they have written. As the Kindly website puts it, the goal is to "end cyberbullying one message at a time." Kindly is the result of a collaboration between Ms. Rao and the UN children's agency, UNICEF, which is developing it as a Digital Public Good. The ITU has several programs that address cyberbullying, including a game for younger children, and training for children, young people, parents, carers and educators. UNICEF has also created an online resource that brings together specialists, international cyberbullying and child protection experts, and teamed up with Facebook, Instagram, TikTok and Twitter, to answer questions and offer advice. — UN News
