What Is Catfishing? How Fake Online Identities Work
Catfishing is the use of a fake online identity to deceive someone. Learn what it means, how it differs from grooming and scams, and how parents can respond.
What catfishing actually means
Catfishing is the use of a fake online identity — an invented name, photos that belong to someone else, a fabricated life — to pull a person into a relationship they would not have agreed to if they knew who was really on the other end.
The deception is not a detail. It is the whole act. A catfish account exists to make someone believe they are talking to someone other than the real person behind it.
Catfishing entered the dictionary through pop culture. The 2010 documentary Catfish, and the long-running MTV show that grew out of it, followed people who slowly realised their online partners were not who they claimed to be. The name itself comes from an old, almost certainly invented story about shipping cod alongside catfish to keep them lively — a parable, not a fact about fish.
By 2014 the term had spread far enough — helped along by the widely reported 2013 Manti Te'o case — that Merriam-Webster added it to the dictionary.
Catfish: a person who sets up a false personal profile on a social networking site for fraudulent or deceptive purposes.
— Merriam-Webster Dictionary
That television-show framing is worth pausing on, because it shapes how most parents picture catfishing: a reveal, a confrontation, a slightly sad stranger who wanted to be someone else for a while.
Some catfishing really is that. But when the target is a teenager, the fake identity is often a doorway rather than a destination — the first move in something else, like grooming, a scam, sextortion, or harassment. The rest of this guide is about telling those apart and knowing what to do.
Catfishing vs. grooming vs. a scam
Catfishing, grooming, and scamming overlap, which is exactly why they get muddled. The clearest way to keep them straight is to separate the method from the goal.
Catfishing is the method: building a false identity. Grooming and scamming are what someone does with the trust that false identity buys — grooming is the patient process of preparing a child for abuse, a scam is the work of separating someone from their money. The same fake profile can be the front end of either.
Grooming is a deliberate effort — usually by an adult, sometimes by an older teen — to build a relationship with a child in order to sexually exploit them. The fake identity, often an adult posing as a teenager, is one of the tools, but the defining feature is the target and the intent: a minor, and abuse.
A scam is about money. In an online romance scam, the fabricated partner exists to manufacture the trust that an eventual request for cash, gift cards, or crypto rides on. It is worth being precise here: online romance scams are one kind of imposter scam, a category the US Federal Trade Commission says cost consumers billions of dollars a year — and those losses fall overwhelmingly on adults, not teenagers. Teenagers are targeted in different ways, covered below.
| Catfishing | Online grooming | Romance scam | |
|---|---|---|---|
| Who is targeted | Anyone — a teen or an adult | A specific child or teenager | Usually adults; teens via games and money-mule recruitment |
| The goal | Varies: attention, validation, revenge, or a setup for something worse | Sexual abuse or exploitation of a minor | Money or access to money |
| Role of the fake identity | The act itself — the deception is the point | A tool to win a child's trust | A tool to build the bond the money rides on |
| A crime on its own? | Usually not, by itself | Yes — a serious crime | Yes once it becomes fraud, extortion, or theft |
| What a parent might notice | A partner who is never on live video | An older "friend" who isolates your teen | Secrecy, then urgent requests for money |
The reason the distinctions matter is practical, not academic. You usually cannot tell a catfish's goal from the outside, especially early on. So the safest stance is to treat the deception itself as the warning sign — and respond to that — rather than waiting to find out which kind of harm you are dealing with.
Why someone would catfish a teenager
People catfish teenagers for four broad reasons. Knowing them helps, because the early behaviour can look identical no matter which one you are looking at.
- Money. One of the fastest-growing online threats to teenagers is financial sextortion: a fake account, usually posing as a peer, coaxes an explicit image and then demands payment to keep it private. When the FBI and its partners issued their December 2022 national public-safety alert, they described over 7,000 reports in a single year, at least 3,000 victims — primarily teenage boys — and more than a dozen suicides; the reports have kept climbing since. Teens are also recruited as "money mules" through fake online relationships.
- Sexual exploitation. A fake identity lets an adult pose as a teenager to reach children who would never knowingly talk to a grown stranger. Reports of this kind of online enticement have climbed steeply — the US National Center for Missing & Exploited Children logged about 1.4 million reports of online enticement in 2025, up 156% on the year before — a count of reports rather than confirmed victims, and one inflated in part by newer reporting laws, but a steep climb by any measure.
- Harassment and revenge. Not every catfish is a stranger. A classmate or ex can build a fake profile to humiliate a teen, lure them into saying something embarrassing, or impersonate them to damage their reputation — closer to cyberbullying than to a scam.
- Loneliness and escape. The "classic" catfish of the TV show: someone, sometimes another young person, who invents a more confident self and gets pulled into maintaining the lie. There is often no plan to extract anything — but the deception is still real, and the fallout for the person on the receiving end is still painful.
Two of these motives are predatory and two are not, and you generally cannot tell which is which from the first weeks of messages. That is the single most important thing to hold onto.
It is also why the right response is not to diagnose the motive but to verify the person — a point the pillar guide's look at where catfishing leads develops in more detail.
Where catfishing happens
Catfishing happens wherever teenagers talk to people they have not met in person — which, today, is almost everywhere. Three arenas come up again and again.
Games and game chat. Online games are now a primary first-contact point, because they put a child in unstructured conversation with strangers who can pose as fellow kids. In 2024, Roblox alone submitted more than 24,000 reports of suspected child exploitation to NCMEC. Platforms like Discord, where private messages are far less visible to parents and moderators, are where those conversations often move next.
Social media. Direct messages on Snapchat, Instagram, and TikTok are the everyday channel. UK police recorded more than 7,000 "sexual communication with a child" offences in 2023–24, and — in the cases where a platform was named — the NSPCC found Snapchat was cited most often. A common pattern is to make first contact on one app and then move the teen to a more private one.
Dating apps. Teenagers are not supposed to be on adult dating apps, but some get on anyway. Age checks vary from app to app and remain imperfect, so a determined under-18 user can still slip through. A profile there carries an extra layer of risk, because the whole premise is meeting a stranger.
How common is it? Common enough to be ordinary. In Snap's 2024 research — a survey of about 6,000 teenagers and young adults across six countries — roughly 30% said they had personally been catfished. The point of that figure is not alarm — it is that this is a normal part of growing up online, and worth talking about as such.
How a fake profile is built
A catfish profile is assembled, not conjured. Understanding the parts makes the whole thing easier to spot — and easier to check.
The photos. The oldest method is theft: lifting attractive, ordinary-looking pictures from a real person's public profile. Stolen photos have a weakness — they exist elsewhere — so a reverse image search will often surface the same face under a different name.
The AI problem. That check is getting harder. Free tools now generate photorealistic faces of people who do not exist, which means there is no original to find. The same wave of technology behind deepfakes has made a convincing fake face essentially free — so a clean reverse-image result is reassuring, but it no longer rules a catfish out.
The backstory. A good catfish gives the persona a coherent life — a job or a school, a hometown, interests that happen to mirror the teen's own. Mirroring is deliberate: it makes the stranger feel like an instant, uncanny match.
The thing they cannot fake. What the persona usually cannot supply is spontaneous, live, unrehearsed presence. A catfish avoids the unplanned video call and the camera turned on mid-conversation. There is always a broken camera, bad signal, a shift at work.
One honest caveat: real-time video used to settle it, and increasingly it does not, because live deepfakes exist. So treat a refusal to appear live as a strong red flag, but treat one short call as a single data point rather than a clean bill of health.
How to respond as a parent
If you think your teen is talking to a catfish, your first move is the conversation, not the device.
The instinct is to confront the relationship and end it. That almost always backfires. The emotional bond is real to your teen even when the person is not, so telling them flatly that the partner is fake usually makes them defend it harder — and quieter.
Open with curiosity instead. Ask who they have been talking to, how they met, how the pace feels. Listening is what earns you the standing to suggest the next step.
One boundary first: these checks are for when something feels off but no line has been crossed yet. If there has already been sexual pressure, a threat, an image shared, money sent, or a request for account access, do not test the person further — go straight to the damage-control steps below.
Otherwise, verify together, framed not as suspicion but as something a real friend would happily go along with:
- A reverse image search of the profile photos, done side by side, so your teen watches the result with you.
- A live, casual video call — and attention to whether the reasons it "can't happen this week" keep stacking up.
- A real-world reference: a friend of theirs your teen could actually meet, a school, a name that leads somewhere.
- A short pause. Suggest going quiet for a day. A real relationship survives it; a manipulator usually escalates or vanishes — and either way you learn something.
If there has already been an ask — money sent, an image shared, account access handed over — the situation has moved past catfishing into a scam or sextortion, and the priority shifts to damage control. Stop further contact and payment, and preserve the profile and messages before anything disappears.
Watch your teen, though, not just the case. If they talk about harming themselves, seem panicked or hopeless, or could be in immediate danger, that comes first — stay with them and contact emergency services or a crisis line (in the US, call or text 988) before you worry about screenshots or reporting. The financial-sextortion cases the FBI describes are frightening precisely because a teen can feel trapped; your calm presence is the thing that breaks that feeling.
One safety rule matters here: if the material involves an intimate image of your own under-18 child, do not forward or copy it, even to keep evidence. Record the account name, link, and time instead, and report through the proper channel. In the US that is the NCMEC CyberTipline (1-800-843-5678), whose free Take It Down service can help limit an image's spread. If the original is already on your teen's device, Take It Down works by creating a digital fingerprint of it on the device itself, without uploading the image — so there is no need to download or copy anything to use it. The pillar's legal and reporting map covers the UK and EU equivalents.
If you decide you want device-level visibility while this is live, make any monitoring open and time-limited — your teen knows the tool is there, what it shows, and when it will be reviewed. Hidden surveillance, once discovered, confirms the very story a manipulator tells: that adults cannot be trusted. Parental controls as scaffolding, not surveillance covers that setup in full.
Whatever you find, keep one message steady: if your teen was deceived, they were targeted by someone practised at it, and they are not in trouble. Shame is what keeps these situations hidden. Calm is what gets them resolved — and it is also what makes your teen willing to tell you sooner the next time something feels off.
Frequently asked questions
What is catfishing, in simple terms?
Catfishing is when someone builds a fake online identity — a false name, photos that are not theirs, an invented backstory — to trick another person into a relationship or friendship under false pretences. The deception is the whole point. It usually plays out entirely through messages, with the catfish always having a reason they cannot meet in person or appear on a live, unscripted video call.
Why is it called "catfishing"?
The term was popularised by the 2010 documentary film Catfish and the MTV series that followed it, in which people discovered that their online partners were not who they claimed to be. The name comes from an old, almost certainly apocryphal story about shipping cod alongside catfish to keep them active — a metaphor, not a fact about fish. The 2013 Manti Te'o case spread the word further, and Merriam-Webster added it to the dictionary in 2014.
Is catfishing illegal?
Pretending to be someone else online is not, by itself, a crime in most places. Catfishing becomes illegal when it crosses into something else: fraud, extortion, identity theft, harassment, or the sexual exploitation of a minor. When the target is a child, the conduct catfishing enables — grooming, soliciting images, sextortion — is very much against the law, regardless of what the fake profile alone would or would not count as.
What's the difference between catfishing and grooming?
Catfishing describes the fake identity; grooming describes what an abuser does with a child's trust. They overlap but are not the same. Between adults or peers, some catfishing is just attention-seeking; but when an adult deceives a child, treat it as a serious safety concern whatever the stated intent. A groomer — usually an adult, sometimes an older teen — deliberately builds a relationship with a minor to sexually exploit them, and a fake identity is often one of their tools. All grooming is abusive. Not all catfishing is grooming.
How can you tell if someone is catfishing you?
The most reliable sign is avoidance of live, unscripted contact: a partner who is never available for a spontaneous video call and always has an excuse. Reused photos that appear elsewhere under other names, a story with details that shift, an intensity that escalates fast, and an early request for money or images are all red flags. No single sign is proof — it is several of them appearing together that matters.
What should I do if I think my teen is being catfished?
Start with your teen, not the phone. Ask who they are talking to and how the relationship feels, without accusation, because the bond is real to them even if the person is not. Then verify together — a reverse image search, a live video call, a real-world reference. If money has changed hands or images have been shared, stop contact, preserve the evidence, and report it. Do not forward or copy any intimate image of a minor.
