Consent banners and dark patterns have become a focal point for privacy regulators across the European Union. As digital platforms increasingly rely on user data for monetization and personalization, concerns have grown around how consent is collected and whether it's truly informed and freely given. Regulators are now taking a closer look at the mechanics of consent banners and the manipulation tactics embedded within them—known as dark patterns.

In recent years, enforcement actions have surged as the EU moves to uphold the principles of the General Data Protection Regulation (GDPR) and the ePrivacy Directive. With the rise of sophisticated user interface designs that nudge users toward accepting tracking or sharing personal data, the spotlight is firmly on how these interfaces are constructed and what constitutes lawful consent. This article explores the latest enforcement trends, the legal context, and what it all means for platform operators and digital marketers.

The GDPR sets the standard for what constitutes valid consent: it must be freely given, specific, informed, and unambiguous. Meanwhile, the ePrivacy Directive complements these rules, especially in the context of electronic communications and cookie usage. Consent banners fall squarely within this intersection.

Dark patterns—design practices that trick users into making decisions they wouldn't otherwise make—are particularly problematic under the GDPR. Whether it’s hiding the “reject” button, using emotional language to encourage acceptance, or presenting choices in unequal visual formats, these patterns undermine genuine user autonomy.

Key Regulatory Guidance

The European Data Protection Board (EDPB) and national data protection authorities (DPAs) have issued specific guidance on consent mechanisms. These include:

Equal prominence for “accept” and “reject” options.
No pre-ticked boxes or default settings.
Easy and accessible ways to withdraw consent.

Platforms using manipulative interfaces to gather consent are now at high risk of investigation and enforcement.

Rise in Investigations and Sanctions

Since 2022, there has been a significant uptick in enforcement actions related to consent banners and dark patterns. Authorities in France, Germany, Ireland, and others have levied fines and issued corrective orders to major tech companies and local businesses alike.

In 2022, the French data protection authority CNIL fined Google and Facebook a combined €210 million for making it more difficult to reject cookies than to accept them. Similarly, the Norwegian DPA fined a dating app for using misleading language and default settings that steered users toward consent.

These cases set important precedents, signaling that regulators will no longer tolerate consent banners designed to exploit user psychology.

Joint Investigations and Cross-Border Coordination

Given the cross-border nature of many digital platforms, European DPAs are increasingly working together. Under the GDPR’s one-stop-shop mechanism, lead supervisory authorities are taking the initiative to address violations that impact users in multiple countries.

For instance, Ireland’s Data Protection Commission (DPC), as the lead authority for many tech giants, has launched multiple investigations into whether consent banners meet the legal threshold—especially in mobile apps and websites with complex tracking infrastructures.

The Role of the European Commission

In parallel, the European Commission has voiced support for stricter regulation of dark patterns, aligning with broader efforts to protect consumers online. The Digital Services Act (DSA), which came into force in 2024, explicitly bans certain manipulative interfaces, reinforcing the GDPR’s principles with additional consumer protections.

Visual and Structural Asymmetry

One common tactic is making the “accept all” button more prominent than the “reject” or “manage settings” options. This can include using brighter colors, larger buttons, or placing options in hard-to-spot corners of the screen.

Forced Continuity and Ambiguity

Platforms often present banners with vague language or confusing structures. Users may be led to believe they must accept cookies to access content, even when alternatives are available.

Misleading Language and Emotion

Consent banners sometimes use emotionally charged or guilt-inducing language to push users toward acceptance—phrases like “support us by accepting cookies” or “help keep this service free” are classic examples.

Hidden Settings

Consent mechanisms may include buried opt-out settings, requiring multiple clicks to refuse consent. Regulators have ruled that such friction undermines the principle of freely given consent.

Impact on Businesses and Platform Design

Legal and Reputational Risk

Companies that fail to redesign their consent banners face not only hefty fines but also reputational harm. Consumers are becoming more privacy-aware, and platforms that ignore usability and transparency risk alienating their user base.

Regulatory penalties can reach up to 4% of a company’s annual global turnover under the GDPR. Additionally, class actions and civil litigation are becoming more common, adding another layer of exposure.

The Need for Privacy-Centric UX

UX and legal teams must now work together to create interfaces that are both compliant and user-friendly. Designing consent banners that truly empower users rather than coerce them is key.

This includes:

Offering clear choices with equal visual weight.
Using plain language to explain data practices.
Providing easy access to settings for withdrawal or modification of consent.

Shifting Toward Standardization and Best Practices

Emerging Industry Standards

Industry bodies, such as the Interactive Advertising Bureau (IAB) Europe, have launched frameworks like the Transparency and Consent Framework (TCF) to help standardize consent across digital advertising. However, these frameworks have also faced criticism and regulatory scrutiny. In 2023, the Belgian DPA declared that the IAB’s TCF did not comply with the GDPR, emphasizing that technical standards must also respect legal principles.

New Tools and Technologies

Privacy tech solutions are emerging to help companies manage consent in a compliant way. Consent management platforms (CMPs) now include features like A/B testing for banner designs, automated audit logs, and real-time user preference updates.

However, simply installing a CMP isn’t enough—platforms must ensure these tools are configured in line with regulatory expectations.

What Comes Next: Future of Enforcement in the EU

A Focus on Behavioral Targeting

As regulators continue to focus on consent banners and dark patterns, particular attention is being paid to behavioral advertising. The widespread use of tracking technologies and user profiling means that obtaining genuine consent is more critical than ever.

Regulators are likely to crack down further on manipulative consent flows in adtech ecosystems, where data is often shared across dozens of third parties.

Increased Role of the DSA

The Digital Services Act introduces stricter rules for very large online platforms (VLOPs), including transparency obligations and auditing requirements. Consent banners used by these platforms will be held to a higher standard, especially in how they relate to recommender systems and content moderation.

Litigation and Collective Redress

With the implementation of the Representative Actions Directive, users and consumer rights groups can now launch collective redress actions. This means that even small infringements in consent collection can become the subject of major lawsuits if patterns of non-compliance are identified.

The growing focus on consent banners and dark patterns highlights a broader shift in the EU’s digital policy landscape—one that prioritizes user autonomy, transparency, and ethical design.

For businesses, this isn’t just a compliance issue—it’s an opportunity to build trust. By abandoning manipulative practices and embracing user-centered design, platforms can meet regulatory requirements while also enhancing user satisfaction.

In an era where every click counts, respecting the user’s right to choose is more than a legal mandate—it’s a business imperative. As enforcement trends continue to evolve, companies must ensure that their consent strategies aren’t just legally defensible, but also ethically sound.
