Cyberbullying among teens happens every day. Harsh words and damaging photos exchanged through texts, email, or social media can result in humiliation, broken friendships, punishment at school, and even legal prosecution. In some cases, online harassment has contributed to suicide. Faced with this frightening problem, parents, educators, and teens are looking for information and advice. But few cyberbullying resources speak to teens themselves. Written by experts in cyberbullying prevention and reviewed by teens, this book provides strategies for kids who are being bullied online--such as save a screenshot of hostile Facebook posts as evidence--as well as for those who have taken part in bullying others. It also presents ways for teens to make their schools and their communities kinder places that are free from online cruelty, for example, by holding a schoolwide "lock it down day" to educate students about Internet privacy. This book gives teens the tools they need to keep themselves and others safe.
