How to Tell if Someone Is Catfishing You

The fastest way to expose a catfish: run their photos through a face search. A catfish's identity is borrowed — the pictures belong to a real person somewhere on the public web. When the face traces back to accounts under a different name, the story collapses. The test takes about 60 seconds.

The 60-second catfish photo test

🕵️ Run the test with Sherlock

  1. Save 2–3 of their photos. Screenshots work. Pick clear, front-facing shots and crop to the face.
  2. Upload each to Sherlock Face Search. The AI compares the face against a billion+ publicly indexed faces across social platforms, websites and news sources.
  3. Check the names on the matches. This is the moment of truth. Same face, different name, different life? You've found the real owner of those photos — and confirmed the catfish.

Reading the results

What to do if you confirm a catfish

  1. Stop responding. Don't confront them with what you found — they'll just move to a new account faster.
  2. Never send money, gift cards, or crypto — and don't "verify yourself" with codes or documents.
  3. Keep evidence. Screenshot the conversations and profile before blocking.
  4. Report the account on the platform, and report financial scams to your local fraud authority (in the US: reportfraud.ftc.gov).
  5. Warn the photo's real owner if you can identify them — their pictures are being misused. Our guide on finding your own photos online can help them too.
Remember: being catfished isn't naïveté — these are professional operations that run hundreds of victims at once. The photo test works because their whole act depends on someone else's stolen face.

Frequently asked questions

What is catfishing?

Pretending to be someone else online using a fake identity — usually built on photos stolen from a real person's public accounts, targeting victims on dating apps and social media.

How do I check if photos are stolen?

Upload them to Sherlock. If the face matches public accounts under a different name, the photos are stolen.

Can a catfish avoid face search?

Increasingly, catfish use AI-generated faces that return no matches. That's why "no results" plus "refuses to video call" should still be treated as a red flag.

Trust, but verify.
