Scam Checker

Scam types explained: a categorised tour of online fraud

Most of the millions of scam attempts that hit inboxes, phones, and dating apps every day are variations on a small number of underlying patterns. This page walks through the most common categories so that the next time something suspicious lands in front of you, you can place it on a map you already know.

Categories overlap. A romance scammer often pivots into an investment scam. A phishing email is also an impersonation scam. A fake online store may direct you to chat on WhatsApp where social engineering takes over. The boundary between "types" is fuzzy — the value of categorisation is recognising the dominant tactic so you can apply the right defence.

Each type below has the same shape: a one-paragraph summary of how the scam works, the most reliable red flags, and links to the deeper guide and the relevant reports feed for that scam family. You do not need to remember any of this in detail. The point is to feel a friction the moment a real example arrives — and to know where to go to verify it.

Phishing scams

Phishing is the broad category of scams that try to trick you into handing over passwords, card details, or one-time codes by impersonating an organisation you trust. Most arrive via email or SMS and direct you to a fake login page.

Red flags for phishing scams

  • Urgency phrasing ("verify within 24 hours")
  • Sender domain that looks similar but not identical to the real brand
  • Links that go to a slightly off URL once you hover
  • Requests for credentials or one-time codes

Impersonation scams

A scammer poses as your bank, a delivery company, the tax office, the police, or a tech-company support team. The goal is the same as phishing — credentials, money, or remote access — but the framing is built around authority instead of urgency alone.

Red flags for impersonation scams

  • Calls or texts claiming to be from a bank but asking you to "transfer to a safe account"
  • Government or tax-office contact via SMS asking for payment
  • Police or court threats demanding immediate fines
  • Tech support unprompted asking to install remote-access software

Investment and crypto scams

Fake trading platforms, "guaranteed return" investments, rug-pull tokens, and pig-butchering long cons. These scams often start on dating apps or social media with a friendly contact who eventually offers an "investment opportunity."

Red flags for investment and crypto scams

  • Promises of guaranteed or unusually high returns
  • A new acquaintance steering you toward a specific platform
  • Pressure to deposit more after a small "successful" withdrawal
  • Withdrawals blocked behind "tax" or "verification" fees

Romance scams

A long-running emotional con where the scammer builds a relationship over weeks or months on a dating app or social network, then introduces a financial emergency or an investment opportunity. Often overlaps with investment fraud.

Red flags for romance scams

  • Refuses video calls or always has a reason the camera "is broken"
  • Story progression that always ends in a money request
  • Claims to be working overseas, on an oil rig, or in the military
  • Pushes communication off the dating app to private messaging quickly

Marketplace and classifieds scams

Buyer- and seller-side fraud on Facebook Marketplace, Gumtree, eBay, Craigslist and similar platforms. Includes overpayment scams, fake shipping companies, "send the item before payment clears," and item-never-arrives cons.

Red flags for marketplace and classifieds scams

  • Buyer offers more than the asking price and asks for a refund of the difference
  • Seller insists on payment via gift cards, crypto, or bank transfer outside the platform
  • Fake shipping or escrow service emails confirming a payment
  • Pressure to "ship today before another buyer commits"

Fake online stores and clone websites

A website that looks like a legitimate retailer — sometimes copied wholesale from the real brand — selling popular items at unrealistic discounts. The store either takes your money and ships nothing, or harvests your card details for resale.

Red flags for fake online stores and clone websites

  • Discounts of 70–90% on popular brand-name items
  • Domain registered very recently but claiming to be "established 2010"
  • Generic email addresses (gmail.com, outlook.com) for support
  • Bank transfer or crypto-only payment methods

Tech support and recovery scams

Fake antivirus pop-ups, cold calls claiming to be from Microsoft or Apple, and "recovery agents" who promise to get your money back from a previous scam — usually by stealing more from you.

Red flags for tech support and recovery scams

  • Pop-up that locks your browser and shows a phone number to call
  • Cold call about a virus or compromised account you cannot verify
  • Anyone asking you to install AnyDesk, TeamViewer, or QuickAssist
  • "Recovery agents" charging an upfront fee to retrieve scammed money
