Online harassment can take many forms — threatening messages, impersonation accounts, defamatory posts, or persistent unwanted contact. When harassment escalates, the ability to document it thoroughly and, where possible, identify the person behind it becomes critical for seeking help from platforms and law enforcement. Reverse face search is a valuable tool in this process: when a harasser uses a real photo, a face search can trace that face across the web, potentially revealing their identity or connecting the harassment to other accounts they operate. This tutorial walks through documenting online harassment systematically, using face search as part of a responsible evidence-gathering process. For related safety guidance, see our article on how to stop cyberstalking with face search.
Step 1: Preserve all evidence immediately
The moment you become aware of harassment, start preserving evidence. Screenshot every message, post, comment, and profile page involved. Each screenshot should capture the timestamp, the username or handle, the full content of the harassment, and the URL of the page. Do not delete messages or block the harasser until you have captured a complete record, because once content is gone, it may be impossible to recover. Use web archival tools to save copies of public pages that could be edited or deleted by the harasser.
Organize your evidence chronologically. Note the date, time, platform, and nature of each incident. This timeline will be the backbone of any report you file, whether to a platform's trust and safety team or to law enforcement. A clear, dated record is far more persuasive than a collection of unorganized screenshots.
Step 2: Identify the harasser's profile photo
If the harassing account uses a real face as its profile photo, this becomes a key piece of evidence and a potential lead to the harasser's identity. Save the clearest version of that photo. If the account uses a stock image, cartoon, or logo instead of a real face, note this — it may indicate an effort to hide identity, and your documentation should focus on other identifying details like usernames, writing style, and behavioral patterns.
Step 3: Run a reverse face search
Upload the harasser's profile photo to facesearching and start the scan. The face search engine compares the face against publicly available web pages — social media profiles, news articles, blog posts, and video content — and returns matches with clickable source links. This can reveal whether the harassing account is a fake using someone else's photos, or a real person whose face appears under their actual identity elsewhere on the web. You can run a face search on facesearching to begin this step.
Step 4: Analyze results for identity connections
Review each match and click through to source pages. If the same face appears on a legitimate social media profile under a real name, that connection may identify the person behind the harassment. If the face appears on a stock photo site, the harasser is likely using a stolen image and the account is fake. Cross-reference usernames, locations, and biographical details to build a picture of who is operating the harassing account.
Documentation is your most powerful tool against harassment. A harasser relies on anonymity and deniability; a thorough, dated record strips both away.
Step 5: Compile a documentation file
Organize all your evidence into a single, clear documentation file. This should include: the chronological timeline of harassment incidents, screenshots with timestamps and URLs, the results of your face search including source links, any identity connections you have found, and notes on the harasser's behavior patterns. A well-structured file makes it easy for platform moderators and law enforcement to understand the scope and severity of the harassment quickly.
- Include the full URL of each harassing post or profile, not just a screenshot.
- Note the platform's reporting mechanisms and whether you have already filed a report.
- Document any patterns — repeated contact across platforms, escalating threats, or impersonation.
- Keep copies in multiple locations in case a device is compromised.
- Record any impact the harassment has had on your safety, mental health, or daily life.
Step 6: Report and take protective action
With your documentation in hand, take action through the appropriate channels. Report the harassment to each platform's trust and safety team, referencing your evidence. If the harassment involves threats of violence, sexual content, stalking, or crosses into criminal territory, file a report with law enforcement and provide your documentation. In cases of persistent or severe harassment, consult an attorney about legal options such as restraining orders or civil action.
Implement protective measures for yourself: strengthen your account security with two-factor authentication, review and tighten your privacy settings, limit what personal information is publicly visible, and consider whether your own photos need monitoring.

Understanding the Limits of Face Search in Harassment Cases
It is important to understand what face search can and cannot do in harassment documentation. If the harasser uses a real, identifiable face, face search may help connect the account to a real person. If the harasser uses a stolen photo, face search can confirm the image is not theirs, which supports a fake-account report. If the harasser uses a cartoon, logo, or AI-generated face, face search may return no useful results, and your documentation should focus on behavioral and contextual evidence instead.
Face search is one tool in a broader documentation strategy, not a solution on its own. It complements screenshotting, archiving, timeline-building, and platform reporting. Used together, these methods create a comprehensive record that gives you the strongest possible case for action.
Safety Considerations During Documentation
While documenting harassment, prioritize your own safety. Do not engage with or confront the harasser, as this can escalate the situation. Do not attempt to contact anyone you identify through face search directly — instead, provide that information to authorities. If you feel physically threatened, contact local law enforcement immediately. Consider seeking support from trusted friends, family, or a counselor, as the emotional toll of harassment is real and should not be faced alone. Your safety always comes before the investigation.
