In the world of social media, from buzzing group chats to public comment sections, a new role has emerged: the digital bystander. These are the people who witness cyberbullying but do not intervene. A bystander might see a classmate being teased in a group chat or read cruel comments on a friend’s photo. Instead of acting, they often choose to stay silent, becoming quiet observers of the online harassment.

Why do people choose to do nothing? Many bystanders hesitate because they are afraid that if they speak up, the bullies will target them next. Others feel unsure about what to say or do to help effectively. Sometimes, they might think it is ‘not their business’ or that someone else will eventually step in. This uncertainty and fear create a powerful barrier to intervention, leaving victims feeling alone.

However, a bystander’s silence is not neutral; it has a significant impact. When nobody objects to the bullying, it sends a message to the victim that everyone agrees with the hurtful behavior. This can make the victim feel even more isolated and ashamed. Furthermore, this lack of opposition empowers the bullies, making them feel that their actions are acceptable and encouraging them to continue their harmful conduct.

Fortunately, being an ‘upstander’—someone who stands up against bullying—doesn't always require a public confrontation. There are safer ways to help. You can report the abusive content to the platform administrators. You can send a private message to the victim, offering your support and letting them know they are not alone. Another powerful step is to tell a trusted adult, like a parent or a teacher, who can provide further assistance and intervene appropriately.
