Cyber bullying involves mean or untrue things being said about someone online or embarrassing photos being shared without consent. To stay safe online, only add people you know on social media, keep your profiles private, don't open suspicious emails, scan USB drives for viruses, avoid giving out personal information, and never meet strangers alone. If cyber bullied, tell an adult, save evidence, don't respond to bullies, and report the behavior to the site or police. People bully for different reasons, so stand up for yourself and know who your real friends are.
