How to Avoid Scams When Buying and Selling Online
The overwhelming majority of classified ad transactions are entirely ordinary. Someone wants a bike, someone else has one, they meet in a car park and money changes hands. But a small minority of listings and buyers are fraudulent, and the patterns they use are consistent enough to recognise once you know them.
What this covers
Key takeaways
- Almost every scam depends on getting you to act before you can verify — pay before inspecting, ship before funds clear, decide before thinking.
- Urgency is the universal warning sign. Legitimate buyers and sellers can wait a day.
- Never refund an “overpayment”. It is one of the oldest frauds and it still works.
- Inspect in person, pay on collection, meet in public.
- A price far below market is not luck. It is bait.
How common are scams, really?
Worth being proportionate about this. Most people who buy and sell through classified ads do so for years without incident. The risk is real but it is concentrated in recognisable situations: high-value items, remote transactions, and anything involving payment before inspection.
Understanding the handful of patterns below removes most of the exposure. They are not sophisticated — they persist because they rely on politeness, hurry and the assumption that other people are acting in good faith.
Scams aimed at buyers
| Pattern | How it works | How to avoid it |
|---|---|---|
| Item that does not exist | Attractive listing, seller cannot meet, asks for a deposit to “hold” it | Never pay a deposit for something you have not seen |
| Fake escrow | Seller directs you to an “escrow service” they control | Never use an escrow service suggested by the other party |
| Stolen goods | Well below market, no receipts, seller vague about history | Ask for proof of purchase; check serial numbers where possible |
| Counterfeit items | Branded goods at implausible prices, stock-style photos | Inspect in person; know what genuine looks like |
| Bait and switch | You arrive and the advertised item is “gone”, another is offered | Walk away. Do not buy something you did not come for |
| Rental fraud | Property advertised by someone who does not own it; deposit requested remotely | Never pay before viewing and verifying ownership |
Any seller who cannot let you see the item but wants money to reserve it is running the oldest scam there is. There is no legitimate reason to pay for something you have not inspected when you are buying locally.
Scams aimed at sellers
Sellers are targeted differently. The goal is usually to extract goods, money, or account credentials.
The overpayment
A buyer sends more than the agreed price — “by mistake” — and asks you to refund the difference. The original payment is later reversed as fraudulent, and your refund is gone. Never refund an overpayment; cancel the transaction entirely.
The courier collection
A remote buyer insists on arranging and paying for their own courier. The item is collected, and the payment later reverses. For high-value goods, only release to a buyer who has paid in a way that cannot be reversed.
The verification code
A “buyer” asks you to read out a code they have sent to prove you are genuine. The code is a two-factor authentication code being used to take over one of your accounts. Never share a code with anyone.
The fake payment confirmation
You are shown a screenshot or an email confirming payment that has not actually been made. Only accept your own bank showing cleared funds.
The off-platform move
Immediate pressure to continue by message app or email, away from any record. Often the prelude to one of the above.

Red flags in a listing
- Price dramatically below anything comparable
- Manufacturer stock photographs rather than the actual item
- A single photograph, or images that look downloaded
- Vague description with no model number, dimensions or condition detail
- No location given, or a location that shifts between messages
- Text copied word for word from other listings
- Seller located far away but keen to ship immediately
- Pressure in the ad itself — “must go today”, “first payment secures”
If a listing photograph looks too polished, search for it. Images lifted from other listings or manufacturer catalogues show up immediately, and that single check filters out a large share of fake listings.
Red flags in a person
The listing may be plausible while the person is not. Watch for:
- Refusal to speak by phone. A brief call resolves more doubt than twenty messages.
- Refusal to meet. For a local sale there is rarely a good reason.
- Elaborate backstory. Working offshore, deployed abroad, moving abruptly — explanations for why normal process cannot apply.
- Poor answers to specific questions. Ask something only an owner would know.
- Pressure and deadlines. “Another buyer is coming at six” is designed to stop you thinking.
- Insistence on one unusual payment method. Especially gift cards, cryptocurrency or wire transfer.
Payment methods ranked by safety
Illustrative ranking of payment methods for private, in-person transactions. Protections vary by country and provider — check what applies where you are.
| Method | Reversible? | Best used |
|---|---|---|
| Cash on collection | Final | Local sales, moderate amounts. Count it before handing over. |
| Bank transfer, cleared | Final once cleared | Higher-value items. Wait for funds in your own account. |
| Card payment | Reversible | Good for buyers, riskier for sellers due to chargebacks |
| Cheque | Reversible | Avoid. Can bounce weeks later. |
| Gift cards | Untraceable | Never. No legitimate transaction uses these. |
| Cryptocurrency | Irreversible | Avoid for private sales. No recourse whatsoever. |
There is no circumstance in which a genuine buyer or seller needs payment in gift cards. If it is requested, stop the transaction immediately. The same applies to any request to buy cards and read out the numbers.
Meeting safely
Choose a public place
Supermarket car park, café, or a police station forecourt — many have designated exchange areas. Daylight hours.
Tell someone where you are going
Share the location and expected time. For higher-value items, take somebody with you.
Inspect properly before paying
Test anything electrical. Check serial numbers. Take the time you need — a genuine seller will not rush you.
Do not invite strangers into your home
Where the item is large and must be collected, have another adult present and keep valuables out of sight.
Trust your instincts
If something feels wrong, leave. No item is worth ignoring that feeling, and you owe nobody an explanation.
Category-specific risks
| Category | Watch for | Check |
|---|---|---|
| Vehicles | Outstanding finance, clocked mileage, cloned plates | Vehicle history check, V5/registration in seller’s name, service records |
| Property rentals | Listings by non-owners, remote deposit requests | View in person, verify ownership, never pay before viewing |
| Phones and laptops | Stolen or network-locked devices | IMEI check, factory reset done, original account signed out |
| Jobs | Advance-fee “training” or equipment costs | No legitimate employer asks you to pay to start work |
| Tickets | Duplicated or invalid tickets | Prefer official resale where the event supports it |
| Pets | Deposit requests, no viewing offered | Always see the animal in its environment before paying anything |
If something goes wrong
Stop all contact and payment
Do not send anything further, however plausible the follow-up explanation.
Contact your bank immediately
Some payments can be recalled if you act quickly. Hours matter.
Keep the evidence
Screenshot messages, the listing, and any payment records before anything is deleted.
Report the listing
Use the report button on the advertisement so moderators can remove it and prevent others being targeted.
Report to the authorities
Most countries have a fraud reporting body. Reports build the picture that leads to enforcement.
Every ad here is reviewed before publication and we remove reported listings that breach our rules. But because we do not process payments, we cannot reverse a transaction or refund you. That is why the precautions above matter.
Frequently asked questions
Is it safe to give my phone number?
A phone call is one of the better verification tools available. If you prefer, keep the conversation in the platform messages until you are comfortable, then move to a call before meeting.
Should I accept bank transfer?
Yes, provided you wait for the money to appear as cleared funds in your own account. Never release goods on a screenshot or a pending notification.
What if a buyer wants to send a courier?
Be cautious with high-value items. If you accept, only release once payment has cleared and is not reversible.
Is a price far below market ever genuine?
Occasionally — house moves and bereavements do produce quick sales. But treat it as a reason to verify more carefully, not less.
How do I report a suspicious ad?
Use the report button on the listing. Every report is reviewed and listings that breach our rules are removed.
Can I get my money back through the platform?
No. We do not process payments, so we cannot refund or mediate transactions. Inspect before paying and use traceable methods.
The short version
See it before you pay for it. Meet in public. Use payment that leaves a trail. Never refund an overpayment, never share a verification code, never buy gift cards for anyone. And when someone is rushing you, that is precisely the moment to slow down.
