Fake trusted influencers: how to spot a misleading collaboration

Updated on 10 March 2026.

Person browsing an influencer’s profile on a smartphone with statistics displayed on screenPartnerships between brands and influencers have become an essential marketing lever. However, behind some seemingly sincere recommendations lie misleading or even fraudulent collaborations. Fake followers, staged reviews, questionable products or concealed commercial practices: consumers can easily be misled. Understanding the mechanisms used by these fake trusted influencers helps avoid risky purchases and costly disappointments.

Influencer marketing turned into a breeding ground for abuse

Influencer marketing is based on a simple principle: recommendations from someone perceived as relatable and credible. This sense of closeness creates a stronger climate of trust than traditional advertising. However, this model also attracts unscrupulous actors who exploit that trust for opaque commercial purposes.

Some profiles artificially inflate their audience by purchasing followers or “likes”. Others promote products without having tested them, or without checking the reliability of the seller. When the commercial relationship is not clearly disclosed, the public may believe the opinion is independent when it is in fact disguised advertising.

In the United Kingdom, regulations require transparency in paid partnerships. The Advertising Standards Authority (UK) reminds advertisers that marketing communications must be clearly identifiable. In the United States, the Federal Trade Commission (US) enforces similar disclosure obligations. Failure to comply with these rules may constitute a misleading commercial practice.

Warning signs of a suspicious collaboration

A misleading collaboration often leaves visible clues for a careful observer. The aim is not to systematically suspect every recommendation, but to identify inconsistencies.

Several elements should raise concern:

  • A sudden and massive increase in followers without any apparent explanation.
  • A very low engagement rate compared to the size of the audience.
  • Generic or repetitive comments, or comments written in a language different from that of the target audience.
  • No clear mention such as “advertisement” or “paid partnership”.
  • A link redirecting to a recently created website with no complete legal information.

These indicators do not always prove fraud, but they justify further checks. Consulting external reviews and searching for reports can help avoid mistakes.

Miracle products and exaggerated promises

Fake influencers often thrive in sensitive sectors: food supplements, cosmetics, trading, cryptocurrencies or weight-loss programmes. The promises are spectacular, the results appear immediate and the enthusiasm seems spontaneous.

However, promoting “miracle products” is a classic scam pattern. Consumers are encouraged to buy quickly through limited offers or exclusive promotional codes. In some cases, these involve hidden subscriptions or free trials that turn into automatic recurring charges.

To better understand these mechanisms, it is useful to refer to official guidance from the National Cyber Security Centre (UK) and the Cybersecurity and Infrastructure Security Agency (US), which outline the main online scams. In addition, problems with a business can be reported to Citizens Advice (UK) or via the FTC fraud reporting platform (US).

The specific case of “free” trials

Misleading collaborations frequently highlight free trials. The influencer claims to have tested the product without risk, encouraging their community to do the same. Yet behind the advertised free offer there may be an automatic subscription that is difficult to cancel.

Before providing your bank details, it is essential to check the terms and conditions and the cancellation policy. Disputes related to these practices are common and can lead to repeated charges.

Influencer or merely a relay for a scam?

Influencer or Scammer?In some cases, the influencer is not personally the originator of the fraud. Some act as relays for brands that quickly disappear after collecting payments. Others accept partnerships without carrying out even basic checks on the partner company.

To reduce risks:

  • Check the company’s legal existence (registration number, verifiable address).
  • Consult independent reviews on several platforms.
  • Verify the age of the merchant website’s domain name.
  • Choose payment methods that offer protection (credit or debit card with chargeback protection, secure third-party payment service).

In the event of serious doubt, a report can be made to Report Fraud (UK) or to the Federal Trade Commission (US).

Legal framework and creators’ responsibility

Legislation is evolving to more strictly regulate influencer practices. The obligation to be transparent about paid partnerships is now clearly established. Creators must also avoid any false or misleading advertising.

Liability may be shared between the influencer and the advertiser. In the case of promoting an illegal or dangerous product, sanctions may include substantial fines. Consumers have avenues for redress, notably through consumer protection organisations or administrative authorities.

Conclusion

Fake trusted influencers exploit digital proximity to promote products or services that may be questionable. Spotting warning signs, verifying the existence of companies and analysing sales conditions are essential reflexes.
