Short answer

Cyberbullying is the repeated use of digital technology — social media, messaging apps, or gaming platforms — to harass, threaten, or exclude another person. Unlike face-to-face bullying, it follows targets into their home at any hour and can reach a vast audience in seconds, leaving a permanent digital record.

How is cyberbullying different from face-to-face bullying?

Both types of bullying involve repeated harmful behaviour designed to harm another person, but digital technology changes the nature of that harm in important ways:

Feature Face-to-face bullying Cyberbullying
Where it happens Physical spaces (school, playground) Anywhere with internet access
When it happens During school hours or specific times 24/7 — even in the victim's bedroom
Audience Limited to bystanders present Potentially thousands online
Anonymity Bully usually known to victim Bully may hide behind fake accounts
Evidence Often no record Screenshots and logs can persist
Escape Possible by leaving the location Much harder — the device is always nearby

The fact that content can be shared, screenshotted, and spread virally means embarrassing or harmful material can reach an audience far larger than the bullying intended, causing disproportionate harm.

What forms does cyberbullying take?

Cyberbullying takes many forms, all involving digital channels:

  • Harassment — sending repeated abusive or threatening messages.
  • Exclusion — deliberately leaving someone out of online group chats or games.
  • Outing — sharing private or embarrassing information or images without consent.
  • Impersonation — creating a fake account pretending to be the target.
  • Flaming — deliberately starting online arguments to provoke or humiliate.
  • Doxing — publishing someone's private personal information (home address, school) online to invite others to target them.

What should you do if you experience cyberbullying?

The most important actions are:

  • Do not respond to the bully — responding often escalates the behaviour and gives the bully the reaction they want.
  • Block the account or sender on the platform immediately.
  • Take screenshots and save evidence before deleting or blocking — dates, times, and message content are important if you report the bullying.
  • Report it to a trusted adult — a parent, carer, or teacher — and also to the platform using its built-in reporting tools. Most social media platforms have a one- or two-click reporting mechanism.
  • Report to the school if the bullying involves classmates, even if it happened outside school hours. UK schools have a legal duty to tackle bullying that affects their pupils.

What are the online reporting tools on major platforms?

Every major platform provides reporting mechanisms. While exact steps change when platforms update their interfaces, the general pattern is:

  • Instagram / Facebook — three-dot menu on a post or profile → "Report" → select "Bullying or harassment".
  • Snapchat — press and hold a message → "Report" → "Harassment".
  • YouTube — three-dot menu on a comment → "Report comment".
  • TikTok — long-press a comment or tap the share arrow → "Report".
  • Online gaming (e.g. Roblox, Minecraft) — right-click the player's name → "Report abuse".

The Childline helpline (0800 1111) and CEOP (Child Exploitation and Online Protection command at ceop.police.uk) provide further support.

What UK laws protect against cyberbullying?

There is no single law called the "Cyberbullying Act", but several existing laws apply:

  • The Malicious Communications Act 1988 — makes it illegal to send electronic communications with intent to cause distress or anxiety.
  • The Communications Act 2003 (s127) — makes it an offence to send grossly offensive, indecent, or threatening messages over a public electronic network.
  • The Protection from Harassment Act 1997 — covers a course of conduct (two or more incidents) that causes alarm or distress, including online.
  • The Computer Misuse Act 1990 — relevant when cyberbullying involves hacking someone's account or spreading malware.

For very severe cases involving threats, the Offences Against the Person Act and the Public Order Act may also apply.

How do you protect yourself online more broadly?

Staying safe online extends beyond cyberbullying:

  • Use strong, unique passwords for each account; use a password manager to remember them.
  • Enable two-factor authentication (2FA) wherever possible.
  • Keep privacy settings set to friends-only on social platforms.
  • Never share your home address, school name, or phone number with strangers online.
  • Be cautious about what photos you share — once online, content can be screenshotted and shared even if you later delete it.
  • Recognise phishing attempts — messages that create urgency and ask you to click a link or provide personal information.

Frequently asked questions

Is cyberbullying illegal in the UK?

There is no single specific "cyberbullying" law, but the behaviour often breaks existing laws such as the Malicious Communications Act 1988 and the Communications Act 2003. Police can and do investigate cyberbullying, particularly when it involves threats, impersonation, or sharing private images. Schools have a legal duty under the Education and Inspections Act 2006 to address bullying that affects pupils, even if it occurs outside school grounds.

Can cyberbullying happen through gaming?

Yes. Online games with voice chat, messaging, and public profiles are common cyberbullying environments. Forms include trash-talking, team-griefing (deliberately sabotaging a teammate), excluding players from groups, and sending abusive messages through the game's chat or friend-request systems. Most gaming platforms have built-in report and mute functions. Do not share personal information in gaming lobbies with people you do not know in person.

What is the difference between online conflict and cyberbullying?

A single argument or a mutual conflict where both parties say hurtful things is unpleasant but is not typically classified as cyberbullying. Cyberbullying involves behaviour that is repeated, deliberate, and one-sided — one person or group targeting another with the intent to cause harm. The repetition and power imbalance are key: a single offensive comment, while harmful, is typically handled differently by schools and platforms than a sustained campaign.

What should I do if I witness cyberbullying happening to someone else?

Being a bystander and doing nothing is sometimes described as tacitly enabling the bully. Safer actions include: not sharing or liking the bullying content (which amplifies it), reporting the content to the platform, telling a trusted adult, and privately checking in with the person being bullied to let them know someone noticed and cares. Direct confrontation of the bully online is rarely helpful and may put you at risk too.
