What Is Cyberbullying?
A gentle introduction for children explaining what cyberbullying means and what they can do about it.
Cyberbullying is never your fault. Save the evidence, block the person, and tell a grown-up.
Cyberbullying is when someone is mean to you on purpose using a phone, tablet, or computer — and they keep doing it. It can happen in messages, games, or on apps. This page helps you understand what cyberbullying is and what to do if it happens to you or a friend.
What Does Cyberbullying Look Like?
Cyberbullying can be lots of things: someone sending you mean messages, sharing embarrassing pictures of you, leaving you out of a group chat on purpose, or saying nasty things about you online. It is not the same as a one-off argument with a friend — cyberbullying happens again and again, and it is meant to upset you.
What to Do If It Happens to You
Do not reply to the mean messages — that often makes things worse. Save or screenshot what was said so a grown-up can see it. Then tell a parent, carer, or teacher what has happened. You can also block the person who is being mean. You will not get into trouble for telling someone — you are doing the right thing.
What to Do If It Happens to a Friend
If you see someone being cyberbullied, do not join in or share the mean messages. Be kind to the person being bullied — send them a nice message or talk to them at school. You can also tell a grown-up what you have seen. Being a good friend means standing up for people when they need it.
If you ever need someone to talk to, you can call Childline for free on 0800 1111.
