Reporting Online Harassment
A practical guide to reporting online harassment, abuse, and stalking to platforms, the police, and other authorities.
Overview
Online harassment — including threatening messages, cyberstalking, doxxing, and non-consensual image sharing — can constitute criminal offences under the Protection from Harassment Act 1997, the Malicious Communications Act 1988, the Communications Act 2003 s.127, and the Online Safety Act 2023. Effective response involves preserving evidence, reporting to platforms, reporting to police, and (where necessary) applying for a civil injunction. Act quickly — digital evidence can be deleted.
Who Can Use This Process
- You are likely eligible to use this guide if your situation involves reporting online harassment.
- You have a genuine legal basis for the matter (contract, tort, statutory right, etc.).
- You have made reasonable attempts to resolve the matter directly with the other party first.
Step-by-Step Process
Preserve and Document All Evidence
Before reporting, preserve all evidence. Take screenshots of every harassing message, post, or account — including the full URL, username, date, and timestamp. Use your device's screen recorder for video content. Download message threads. Create a harassment log recording each incident with date, time, platform, what was said, and links to evidence. Do not delete messages — even if distressing, they are evidence. Store everything in a secure location (cloud storage, encrypted folder).
- Screenshots should show the full URL bar (copy the URL separately as well)
- For Twitter/X, Instagram, and similar platforms, the platform reference ID in the URL is unique and persistent
- The Internet Archive (archive.org) can preserve web pages
- Digital forensics companies can extract and certify evidence for legal proceedings if needed
Report to the Platform
Report each piece of harassing content to the platform concerned using the in-platform reporting tools. Major platforms (Facebook, Instagram, X/Twitter, TikTok, YouTube) have dedicated reporting mechanisms for harassment, threatening behaviour, and non-consensual content. Keep a record of the reference number each report generates. Under the Online Safety Act 2023, major platforms have duties to protect users from illegal content including harassment, threats, and stalking.
- Screenshot the platform's response (or non-response) — evidence of reporting
- If the platform is slow or ineffective, escalate to OFCOM (the Online Safety Act regulator) under the new user reporting complaints mechanism
- For non-consensual intimate images (revenge porn), contact the Revenge Porn Helpline (0345 600 0459) — they have direct contacts with major platforms for rapid takedown
- For child sexual abuse material, report to the Internet Watch Foundation (IWF) at iwf.org.uk
Report to the Police
Report online harassment to the police, either at a local police station or via 101 (non-emergency) — or 999 if there is immediate risk of harm. Provide your evidence log, screenshots, and any identifying information about the harasser. The police can investigate under the Protection from Harassment Act 1997, the Malicious Communications Act 1988, the Communications Act 2003, or the Stalking Prevention Act 2019. Obtain a crime reference number for every report.
- Report even if you think the police are unlikely to act — a crime reference number establishes a record and may be needed for a civil injunction
- Request that the police obtain IP address or account data from platforms before it is deleted — platforms retain data for limited periods
- If the police are slow to act, escalate to the force's Professional Standards Department or your local police and crime commissioner
- For serious stalking, the police can apply for a Stalking Protection Order (SPO) under the Stalking Protection Act 2019
Consider Action Fraud (Financially Motivated Harassment)
If the online harassment has a financially motivated element — blackmail, extortion, romance fraud, investment fraud — report to Action Fraud (0300 123 2040 or actionfraud.police.uk). Action Fraud refers cases to the National Fraud Intelligence Bureau (NFIB) and the relevant police force. Sextortion (blackmail using intimate images) should be reported to both the police and Action Fraud.
- Never pay blackmail demands — it rarely stops the harassment and encourages further demands
- Screenshot all demands including payment account details — these are evidence

Apply for a Civil Injunction if Necessary
If police action is slow or insufficient, you can apply to the County Court for a civil harassment injunction under s.3 of the Protection from Harassment Act 1997. An emergency ex parte injunction (without notice to the harasser) can be obtained within 24–48 hours in urgent cases. Breach of the injunction is a criminal offence (up to 5 years' imprisonment — s.3(6) PHA).
- A civil injunction provides protection even if the criminal justice system does not act
- The civil standard of proof (balance of probabilities) is lower than the criminal standard
- Many solicitors work on a Conditional Fee Agreement (CFA) for harassment injunctions
- The National Stalking Helpline and organisations such as Paladin can provide advocacy support
Seek Support and Take Care of Yourself
Online harassment has significant psychological impact. Seek support from friends, family, and specialist services. Consider informing your employer, school, or university if the harassment is affecting your work or studies. Take practical steps to improve your online safety: lock down social media privacy settings, change passwords, enable two-factor authentication, and be cautious about what personal information you share online.
- The Samaritans (116 123) provide 24/7 emotional support
- Paladin National Stalking Advocacy Service (020 3866 4107) provides specialist support for stalking victims
- Record the impact of the harassment on your mental health — this is relevant if you later seek damages
- Consider a digital audit of your online presence to reduce your attack surface

Important Warnings
Do not delete evidence in the hope the problem will go away — screenshots and logs are essential for any legal or police action.
Retaliating or counter-harassing will undermine your position in any legal proceedings.
If you are at immediate risk of harm, call 999 — do not wait to report through online forms or non-emergency channels.
