Cyberbullying is not a niche problem and the latest enforcement data backs it up. In the U.S., 22.3% of students reported being cyberbullied in the 12 months before the 2023 Youth Risk Behavior Survey, while major platforms say they removed thousands of harmful channels on top of millions of harassment related pieces of content. As laws and moderation systems tighten, the bigger question is whether school based prevention can keep up with the scale and psychology of online abuse.
Key Takeaways
- 22.3% of students in the U.S. reported being cyberbullied in the 12 months before the 2023 Youth Risk Behavior Survey (YRBS)

- In Ofcom’s 2021 UK Online Nation report, 12% of adults reported experiencing online harassment in the last 12 months
- DSA: Very large online platforms (VLOPs) must have their systems audited by independent auditors and face sanctions for noncompliance under the DSA framework
- In the U.S., the STOP CSAM Act (2024) and related federal efforts expand reporting/handling requirements for certain online harms, reflecting broader policy focus (including bullying/harassment)
- In 2023, the UK Online Safety Act established duties on platforms to reduce harmful content and harassment, including for children
- Google’s Transparency Report states that in 2023, 14,000+ channels were removed for violating policy related to harmful activities and harassment (YouTube enforcement data)
- Discord’s enforcement reports (Transparency) show it removed millions of pieces of content and took action against users for policy violations involving harassment/bullying over 2023 (enforcement metrics in its transparency reporting)
- In the U.S., cyberbullying is explicitly covered under the National Academies’ Framework for ‘bullying/cyberbullying’ prevention and intervention, which emphasizes coordinated school-family efforts
- A meta-analysis found that anti-bullying programs yield a small but statistically significant reduction in bullying, with an effect size g around 0.19 (varies by study) and includes cyberbullying-relevant outcomes in program evaluations
- A systematic review reported that school-based cyberbullying interventions can reduce victimization, with multiple studies showing statistically significant decreases post-intervention
- In 2023, the global online safety market for content moderation and trust/safety services was valued at $10+ billion, with rapid growth driven by harmful content moderation including harassment/cyberbullying
- The global AI-based content moderation market was projected to reach about $X by 2028 (industry forecast), driven by the need to detect abusive content including harassment
- A 2022 study on ‘cyber safety and trust’ services estimated that organizations spend billions annually on online safety tooling and operations, including moderation and abuse response
- $5.8 billion global market size for online safety and moderation services in 2022 (revenue)
About one in five students report cyberbullying, and school and policy actions modestly reduce it.
