CNMC Takes Action Against Influencers for Misleading Advertising Practices
The recent actions taken by Spain’s National Markets and Competition Commission (CNMC) mark a significant shift in how influencers are held accountable for their advertising practices. The CNMC has summoned five prominent influencers, including Sofía Suescun, Lola Lolita, Tamara Gorro, Peldanyos, and Samantha Vallejo-Nágera, for allegedly failing to adequately disclose paid promotions in their content.
The Issue of Hidden Advertising
The primary concern raised by the CNMC stems from misleading advertising practices that blur the lines between organic content and paid promotions. Influencers have been found to promote products—ranging from bank cards to clothing—without clearly indicating their commercial nature within videos. This misrepresentation can deceive viewers and violates ethical advertising guidelines.
Key Findings of the CNMC
The CNMC’s investigation revealed that many influencers employed vague labeling techniques to obscure their collaborations. These strategies included terms like “ad” and “ambassador,” using external tags like “publi,” or placing notices in less visible areas of their content. However, the CNMC maintains that simply mentioning these terms is insufficient if they are not visibly integrated into the content.
Clear Labeling Requirements: The CNMC emphasizes that labels such as “advertising” or “publi” must be prominently displayed within videos to be considered valid.
Definition of Commercial Communication: The resolution also clarifies that commercial communication is not solely dependent on compensation. Even if a brand does not provide direct payment, the promotion can still carry advertising purpose.
Evolving Interpretative Criteria: As of June 2025, stricter interpretive criteria will be applied, expanding the regulatory scope over social media publications and requiring better transparency from influencers.
Broader Implications for Influencers
These recent developments signal an increased scrutiny in the influencer marketing landscape, as many creators are operating outside the so-called “influencer law.” The CNMC aims to create a level playing field where all influencers, regardless of their size, adhere to the same advertising guidelines.
The Reaction of the Influencers
Influencers have expressed their views regarding the CNMC’s findings. Samantha Vallejo-Nágera acknowledged a “specific oversight” in her case, while Tamara Gorro claimed that her status as a “brand ambassador” meant she was not obliged to disclose promotions in every instance. This led to a critical review from the CNMC, which found such defenses inadequate.
Conclusion
This crackdown by the CNMC marks a broader movement towards improving transparency and accountability in influencer marketing. As the delineation between genuine content and advertising continues to blur, it’s vital for influencers to adapt to these regulations to maintain credibility with their audiences. The outcomes of these changes could fundamentally reshape the influencer marketing industry in Spain and potentially set a precedent for similar actions in other countries.
