What Is Cyberbullying? A Clear Guide To Recognition, Impact, And Response In 2026

Definitions and examples here draw on UNICEF’s guide to stopping cyberbullying and PACER’s cyberbullying overview, which draws on StopBullying.gov.

What is cyberbullying? It is bullying with digital technologies: repeated behaviour aimed at scaring, angering or shaming the person targeted. The practical response is to save evidence, block the sender and report on the platform.

Fake accounts and impersonation sit close to online scams, so the hub’s guidance on how to spot a phishing email is a useful companion read.

Effects and practical decisions

Cyberbullying is common enough among young people that it deserves a plan before it happens. A 2021 study of 2,500 US middle and high school students, reported by the National Children’s Alliance, found that 45.5% said they had been cyberbullied in their lifetime. That is one survey of one group, so it shows how widespread the experience can be among students rather than giving a figure for everyone.

The National Children’s Alliance also stresses that cyberbullying is not just teasing. It describes a pattern of purposely harmful behaviour targeting an individual and using technology. KidsHealth words it in a similar way, defining cyberbullying as the use of technology to harass, threaten, embarrass or target another person. Harassment is therefore the everyday label for much of what happens, and it can arrive as texts, posts, comments or fake profiles.

These definitions lead to a few decisions that matter more than the label itself:

• Judge the pattern, not the intent claimed. A sender who says it was a joke does not change the fact that repeated behaviour meant to scare, anger or shame is the core of the definition. Treat repetition as the signal to act.
• Treat the record as an asset. UNICEF notes that cyberbullying leaves a digital footprint, a record that can prove useful as evidence. The same permanence that makes online humiliation hard to escape also makes it easier to document.
• Do not wait to identify the sender. Because cyberbullying can be done anonymously, an unknown name should not delay saving what you can see and using the platform’s own tools.
• Look at what others can already find. If personal details have been exposed, it helps to understand what is publicly visible; How To Check Your Digital Footprint: A Practical 2026 Guide To Finding What Others See – Internetbuttons explains how to look.

With those decisions in mind, it helps to know the forms the behaviour takes and the places it appears.

Common forms and where they appear

UNICEF says cyberbullying can take place on social media, messaging platforms, gaming platforms and mobile phones. Social media platforms combine public posts with private messages, while messaging and gaming spaces are closer, faster and often less visible to other people. A person being targeted in one place is often exposed in others, so the safest assumption is that every channel they use is in scope.

Public humiliation and false stories

UNICEF’s examples include spreading lies about someone and posting embarrassing photos or videos of them on social media. PACER, whose list is sourced to StopBullying.gov, adds posting comments or rumours that are mean, hurtful or embarrassing. The harm comes from audience: once a post is visible to others, the target may feel they have lost control of their own reputation.

Impersonation and fake accounts

UNICEF describes impersonating someone and sending mean messages to others on their behalf or through fake accounts. This form is hard to spot from the inside, because friends may receive hurtful messages that appear to come from the target. If you are the person being impersonated, tell the platform that the account is not yours and report it, rather than trying to deal with each recipient first.

Threats, hateful content and doxxing

PACER also lists threats and hateful content among common tactics. Doxxing is a separate and especially invasive form of online harassment: it means making someone’s personal information public, including addresses and phone numbers. Because it exposes details that can be misused, it calls for a quicker and firmer response than a rude comment does.

Whatever the form, the first signals often appear in a person’s behaviour rather than on a screen.

Early signs worth a conversation

The National Children’s Alliance lists warning signs that include hiding or being unusually secretive about online activities, withdrawal, and changes in school performance and in how a platform is used. Those signs do not always point to cyberbullying, but they definitely point to a conversation. That wording is a useful rule: treat signs as a reason to talk, never as proof.

A few practical choices follow from that:

• Start with curiosity. Ask what has changed, rather than accusing someone of hiding something. Secrecy about online life can have other causes, and an accusing tone makes it harder to hear the real one.
• Watch for clusters. One sign on its own is weaker evidence than several appearing together, such as withdrawal alongside a change in how someone uses an app.
• Bring in family-level safety guidance when the person is a child. The parent-focused guide Keeping Kids Safe Online: A Practical Internet Safety Guide For Parents And Guardians (2026) – Internetbuttons covers wider online safety habits that support these conversations.

If the conversation confirms that something is happening, the next step is to act on it with the tools the platform already provides.

Reporting and blocking, step by step

UNICEF advises considering blocking the bully and formally reporting their behaviour on the platform itself. The National Children’s Alliance confirms that online platforms and social media have built-in mechanisms to report harmful behaviour. In its guide, UNICEF quotes Meta as saying that the company takes bullying and harassment situations seriously, which is a reason to use the in-app route rather than assume nothing will happen.

1. Collect evidence. UNICEF suggests keeping text messages and screenshots of social media posts. KidsHealth likewise recommends saving evidence of the bullying if you can.
2. Block the sender. KidsHealth notes that most devices have settings that let you electronically block the bully or bullies from sending notes, so blocking can be done at device level as well as inside an app.
3. Report inside the platform. Use the platform’s own reporting mechanism for the post, message or account, and attach what you saved if the form allows it.
4. Report texts and emails to the provider. KidsHealth says abusive texts or emails should be reported to the phone service or email provider.

Blocking and reporting work together. Blocking reduces what reaches the person right away, while a report gives the platform a chance to act on the account or content. Saving evidence first matters because blocking can remove the messages from easy view.

Using the tools with assistive technology

Report and block tools are only useful if you can reach them. If a menu is awkward with a screen reader, magnifier, switch device or voice control, try the device-level block settings, which are separate from any single app. A trusted person can also sit with you and operate the report form while you decide what to include. Keep the evidence in a format you can read comfortably, such as saved screenshots with short notes you or a helper add.
