Second-hand site scams: the most effective protection?

With the rise of e-commerce, second-hand platforms have become very popular as they enable users to conveniently buy or sell all kinds of goods. But this enthusiasm is also attracting ever more ingenious scammers, who seek to trick users. The most common frauds include fictitious sales, off-platform transactions or unusual payment requests. Fortunately, they can be identified and behaviour can be adopted that limits the risk. Here are our tips to help you secure your transactions.

The most common scams

Scams on second-hand platforms often exploit user trust by means of very credible ads.

Common pitfalls include fictitious sales where the so-called seller disappears after receiving the payment. These ads feature very attractive offers, such as a high-value product sold at an unbeatable price.

Another method: the fraudster offers to continue the discussion or transaction outside the official platform. By claiming to avoid additional charges, he persuades the buyer or seller to use direct payment or private messaging. Unfortunately, these arrangements often end with the victim losing their money and having no recourse possible.

Some scammers add a touch of sophistication by charging extra fees for fictitious services, such as shipping or having a parcel delivery company release the delivery. They are very quick to produce fraudulent supporting documents to make their scams seem all the more convincing. Similarly, some ask for a down payment to “book” an item or secure the transaction. The end result is always the same: once the money is transferred, the fraudsters disappear. 

Warning signs not to be ignored

While scams are becoming more sophisticated, there are often clues to help you expose them. Take great care when you see overly advantageous prices or when dealing with people who are in a hurry and want to finalise the transaction quickly. Also be wary of people who insist on leaving the platform's secure framework.

Another red flag is requests for payments that are unusual or via unconventional means. If your contact proposes alternative solutions not provided for by the site, this may be a sign of attempted fraud. Finally, remain vigilant when it comes to supporting documents that seem too perfect: these documents are often simple fabrications designed to mislead you.

Adopt the right reflexes

To limit risks, always carry out transactions on the official platform. These sites often include security features to protect payments and resolve disputes. If someone asks you to bypass this system, it could signal an attempt at fraud.

Categorically refuse to pay any unforeseen costs, whether for delivery, insurance or booking. A reliable platform generally includes all these costs in the final price displayed. Also take time to check the profile of the person you are talking to: a recent account with little activity or negative comments may be a red flag.

When you come across an ad that interests you, do not hesitate to look on other sites to see whether it is used in other fraudulent ads. This type of approach can save you a lot of trouble.

The five golden rules to secure your transactions

To reduce the risk of fraud, always follow these five key security principles:

  1. Never share your bank account details or sensitive information with anyone, no matter what reason they put forward for asking you to do so.
  2. Use only the means of payment and messaging system offered by the platform.
  3. Beware of offers that seem too good to be true.  
  4. Make sure you check your devices and software regularly to avoid security breaches.
  5. If in doubt, contact the platform’s customer service department or ING directly.
