What Is a Catfish Online? The Complete Guide

Where the term comes from

The term catfishing entered common usage after the 2010 documentary Catfish, which followed a man who discovered the woman he had been communicating with online had invented her entire identity. Since then, the term has been widely adopted to describe anyone who creates a deceptive online persona to form false relationships.

Why people catfish

The motivations vary widely. Some catfish are driven by loneliness or insecurity and create idealised versions of themselves they feel more confident presenting. Others are running deliberate financial fraud, building emotional trust before extracting money. Some are collecting personal information for harassment or blackmail. And some are simply bots operated by scam networks targeting large numbers of people simultaneously.

Financial fraud is the most financially damaging category. Romance scams, where a catfish builds a relationship over weeks or months before introducing a financial crisis, cost victims billions globally each year. The FBI recorded over $1.14 billion in romance scam losses in 2024 alone.

What catfishing looks like

• ▸Profile photos that are too polished: every photo looks professional, with no casual or candid shots.
• ▸Refusal to video call, with a rotating set of excuses that never resolve.
• ▸Moving very fast emotionally: declarations of love or deep connection within days.
• ▸Always busy when you suggest meeting in person.
• ▸A job or location that conveniently explains why they can't meet: deployed military, doctor abroad, oil rig engineer.
• ▸Eventually introducing a financial crisis or investment opportunity.

The most reliable ways to spot one

Reverse image searching a profile photo takes under a minute and immediately reveals stolen images. If the same face appears elsewhere under a different name, the profile is fake. For AI-generated photos, which don't appear in any reverse search, an AI analysis tool examines the image for generation artefacts invisible to the human eye.

In conversation, ask specific questions about their life that would require genuine personal knowledge. Catfish running multiple victims simultaneously lose track of details and deflect specific questions. Insisting on a live video call before any real emotional investment forms is the single most reliable verification method.

What to do if you're being catfished

Don't confront the person directly. They will block you and move on. Instead, stop all contact, report the profile on the platform using its built-in report function, and if any money has been sent, contact your bank immediately. Report the scam to your national fraud authority: in the US, that's the FTC at reportfraud.ftc.gov and the FBI at ic3.gov. In the UK, report to Action Fraud. In Australia, to Scamwatch.
