How to Spot a Grifter: Warning Signs, Common Scams, and What to Do

Grifters count on your trust—and your hesitation. Here's how to recognize their tactics before it costs you.

By , Attorney Mitchell Hamline School of Law

Grifters don't announce themselves. They show up as friendly strangers, convincing salespeople, or even seemingly official institutions. By the time you sense something is wrong, the damage is often done. A grifter (also called a con artist, swindler, or scammer) relies on one thing above all else—your trust. Whether the contact came via phone, email, social media, or in person, the warning signs are remarkably consistent. Knowing what to look for and what questions to ask can help you avoid falling prey to many scams.

What Is a Grifter?

Grifters are lawbreakers who have a knack for swindling, tricking, and deceiving others. Instead of stealing or taking something by force, grifters convince their victims to willingly hand over money or possessions.

No matter what you call it, grifting is a crime. In legal terms, it falls under theft, larceny, swindling, or fraud, depending on how your state defines these offenses. State theft laws cover a broad range—from physically taking someone's property without consent to theft by deception. Grifters can't claim innocence on the grounds that their victim willingly handed over money, though, because consent obtained through trickery isn’t legally valid.

Common Grifter Phrases and Pressure Tactics

Grifters are skilled communicators who excel at convincing you to do something you had no intention of doing. Certain phrases and behaviors are reliable warning signs.

Watch out for these tactics by grifters:

  • Today only! Legitimate opportunities rarely require an on-the-spot decision. Never give in to pressure to decide fast because the deal is "disappearing tomorrow."
  • Cash only. Reputable vendors and businesses do not operate on a cash-only basis for significant transactions. Cash leaves you with no recourse.
  • Get-rich-quick schemes. The only person getting rich quickly is likely the one scamming you. Promises of something for nothing are a classic grifter signal.
  • Right place; right time. Someone who "just happens to be in your area" with an unsolicited offer and a convenient backstory has actually planned it all. And it’s definitely too good to be true.
  • Charity scams. Scammers exploit generosity. Always verify a charity independently before donating. A legitimate organization will give you a name and website you can check yourself.

Note these behavioral red flags of grifters:

  • are unusually friendly and courteous right away
  • will rush you to make a decision
  • have a compelling "down-on-my-luck" story designed to elicit sympathy
  • claim "everyone else" who invested made money
  • guarantee a profit
  • try to isolate you from friends, family, or advisors who might raise doubts

Be especially vigilant when the grifter initiated the contact.

Why Grifting Tactics Work

Understanding why grifters succeed can help you understand their tricks. It also removes the shame from being targeted. Grifters don't succeed because their victims are foolish. They succeed because they're skilled at exploiting human psychology.

They trigger your emotions, not your logic. Grifters deliberately manufacture emotional states—excitement, fear, sympathy, or urgency—because strong emotions impair rational decision making. The "today only!" pressure isn't really about scarcity. It's about cutting off the time you'd need to think clearly and ask questions.

They exploit authority and social proof. Humans are wired to trust people who seem familiar, friendly, or authoritative. Grifters invest heavily in appearing credible by using official-looking letterhead, referring to recognizable institutions, or claiming that "everyone else" who participated made money. If others did it and it worked, the thinking goes, it must be safe (also called “herd mentality”).

They use guilt and obligation. Many scams begin with a small gift, favor, or "free" offer. When someone does something for us, we feel the obligation to return the favor, even to a stranger. A grifter who "helps" you first is laying the groundwork for when they make their real ask.

They target moments of vulnerability. Grifters often seek out people who are grieving, in financial distress, lonely, or going through a major life transition—looking for key moments when people crave solutions, connection, and hope.

They use distraction. A grifter might distract you with a compelling story, a flattering compliment, or a sense of crisis to keep you from asking the obvious questions.

Recognizing these triggers—urgency, authority, guilt, vulnerability, and distraction—gives you the awareness to pause before acting and getting scammed.

Examples of Common Grifter Schemes

Grifters thrive by fitting in and appearing to be something they’re not. Scams often look legitimate at first glance, even appearing to come from a reputable source like your bank or a government agency.

Bank impersonators. Your bank will never send you an email saying something is wrong with your account, asking you to verify your password, or prompting you to click a link. If you receive such a message, go directly to your bank's website by typing the address yourself and contact customer service from there.

Government impersonators. Scammers send official-looking mail or emails mimicking the IRS, Social Security Administration, Medicare, or law enforcement. Read anything you receive carefully and look for the pressure phrases listed above, odd formatting, or typos. When in doubt, call the agency directly using a number from its official website—not one provided in the message.

Digital arrest scams. Digital arrest scams are a growing threat. Scammers use AI-generated deepfake videos and forged documents (including fake court orders or arrest warrants) to convince you that you're under investigation and must pay immediately to avoid arrest. Real law enforcement agencies don’t demand payment over the phone or by email.

Fake online storefronts. Scam websites use slick designs, fake reviews, and stolen product images to sell goods that never arrive or are cheap counterfeits. Stick to retailers you know, verify web addresses carefully, and pay by credit card so you can dispute charges.

Online and Digital Grifting Red Flags

The internet and AI have given grifters an enormous new platform and tools that make their schemes look more legitimate than ever.

Phishing scams. Phishing isn’t new—it’s just more sophisticated and much harder to identify. Phishing occurs when someone disguises a communication (an email, text message, phone call, or fake website) as a legitimate message from a trusted source to trick recipients into revealing sensitive personal information. Never click links in unsolicited communications. Go to the website on your own to check it out.

AI-generated scams. Artificial intelligence now allows grifters to clone voices, generate realistic photos of fake people, and write flawless, personalized messages. You might receive a voicemail that sounds exactly like a family member saying they're in trouble and need money wired immediately—called a "vishing" (voice phishing) attack. If something feels off, hang up and call that person directly on a number you already have.

Romance scams and "pig butchering." Pig butchering refers to a scam where the grifter gains the victim's trust over time (fattens them up) before exploiting them (butchering). A stranger connects with you on a dating app or social media, builds a warm relationship over weeks or months, and then introduces you to a can't-miss investment opportunity—possibly involving cryptocurrency. This is a common pig-butchering scheme designed to build emotional trust before taking everything you have.

Watch for these red flags in all digital communications:

  • urgent subject lines ("Your account has been suspended," "Action required today")
  • requests to move a conversation off-platform (from a dating app to WhatsApp, for example)
  • unsolicited messages offering jobs, prizes, or investment opportunities
  • poor grammar, mismatched logos, or slightly misspelled domain names
  • requests for payment via wire transfer, gift cards, cryptocurrency, or mobile wallets—all of which are nearly impossible to recover
  • pressure not to tell family or friends about the deal or opportunity

If you receive an unsolicited message that creates urgency, requests secrecy, or asks for money in any form, treat it as a scam until you can independently verify every detail.

How to Protect Yourself From Grifters

Approach every interaction you didn’t initiate with a dose of healthy skepticism. Assume the other party may be hiding the truth until you can confirm facts.

  • Ask for the offer and all its terms in writing, on official letterhead.
  • Ask for the background, track record, and credentials of the people behind the deal.
  • Ask to see a balance sheet or bank references before making any investment.
  • Get the full name of the person you're speaking with, a callback number, and an email address.

If the person is uncomfortable answering any of these questions or refuses to put anything in writing, you’re almost certainly dealing with a grifter. Put yourself on high alert if the person tries to downplay risks, deflect your questions, or discourage you from consulting anyone else.

When to Consult an Attorney and Where to Report

If something feels too good to be true, trust your gut—it probably is.

Get legal advice. Before you get involved in any significant project, deal, or investment—and especially before you send any money—consult an attorney. A lawyer can help you objectively evaluate risks and protect your interests. Better yet, simply tell the person you plan to contact a lawyer and watch what happens.

Research. Most states offer information on possible scams and assistance through their attorney general's offices or consumer protection agencies. The FTC's website also maintains up-to-date scam alerts.

Report it. If you believe you've been victimized, contact your local police department, your state attorney general's office, or file a report with the FTC at ReportFraud.ftc.gov. For online and digital fraud, you can also file a complaint with the FBI's Internet Crime Complaint Center at ic3.gov.

Grifters violate state and federal fraud laws. The sooner they're reported and apprehended, the fewer people they can victimize.
