Deceptive and Unfair Advertising

The totality of deceptive and unethical advertising practices that obstruct consumers' judgment and exploit information asymmetry

Deceptive and Unfair Advertising

Overview

Deceptive and unfair advertising (Korean: 비열한 광고; 卑劣한 廣告, deceptive & unfair advertising) is a blanket term for advertising and marketing practices that intentionally obstruct consumers from making rational judgments or exploit information asymmetry for gain. Going beyond simple exaggeration or embellishment, it includes techniques that use any means, such as false information, psychological pressure, and interface manipulation (dark patterns), and is a major regulatory target under labeling and advertising laws, fair trade laws, and consumer protection laws in various countries.

1. Concept and Boundaries

Advertising is inherently selective information delivery. All advertising highlights the strengths of one's product and downplays its weaknesses. The problem arises when that emphasis causes consumers to misunderstand or blocks the opportunity to compare alternatives in the first place. In other words, the core criterion for deceptive and unfair advertising lies not in 'is it false?' but in 'did it allow consumers to exercise their right to know?' Accordingly, stating facts while cunningly omitting context, hiding that something is advertising, and designing processes to make withdrawal or cancellation difficult are also included in the broad sense of deceptive and unfair advertising.

2. Representative Types

① Bait and switch — After attracting customers with exceptionally low prices or conditions, it induces them to switch to higher-priced products on grounds of sold-out inventory or unmet conditions. The bait itself is often fictitious from the start.

② Disguised/native advertising — It borrows the format of articles, reviews, expert columns, or influencers' daily content and does not clearly disclose that it is advertising. This is a typical deception that borrows credibility from the content format.

③ Dark patterns — UI designs that hide subscription cancellation buttons, make the cancellation path convoluted over multiple steps, manipulate urgency with countdown timers, or set pre-checked opt-out options as defaults.

④ Fear and anxiety marketing — It stimulates vague fears about disease, aging, appearance, or social exclusion to induce unnecessary products or excessive treatment. It is a recurring problem in the health functional food, beauty, and insurance sectors.

⑤ Comparative and disparaging advertising — It compares by picking out only the weaknesses of competitors' products or claims unsupported superiority and damages the other party's credibility. Even if true, if the comparison criteria are manipulated, it constitutes unfair labeling and advertising.

⑥ Manipulated social proof — Fake reviews, bulk-purchased reviews, failure to disclose compensation for experience group reviews, false sales volume or number of students, etc.

⑦ Targeting vulnerable groups — Advertising that induces children's pester power, inducing high-value payments by exploiting older adults' digital vulnerability, etc.

3. Why It Is a Problem

Deceptive and unfair advertising goes beyond individual consumers' financial losses and erodes the trust foundation of the market. Businesses that honestly provide information become disadvantaged in competition, and consumers come to doubt all advertising, sharply increasing search costs. As a result, a 'lemon market' structure is formed in which the efficiency of the entire advertising industry and the social trust capital are damaged together.

4. Regulation and Remedies

In Korea, the Act on Fair Labeling and Advertising prohibits false or exaggerated, deceptive, unfairly comparative, and disparaging advertising, and the Korea Fair Trade Commission imposes corrective orders and surcharges. In addition, the Act on Consumer Protection in Electronic Commerce governs disclosure of important information and the right of withdrawal, and the Act on Door-to-Door Sales regulates labeling obligations for multilevel and sponsored door-to-door sales. Since 2024, dark pattern regulation has emerged as a key agenda in discussions on revising the Electronic Commerce Act; the EU directly regulates dark patterns through the Digital Services Act (DSA) and the Unfair Commercial Practices Directive (UCPD), and the U.S. FTC has also introduced the 'click-to-cancel' rule.

5. Consumer Response

For content where the boundary between advertising and information is ambiguous, check affiliate/advertising disclosures first.
For comparative advertising, check the criteria: 'what is being compared with what, and under what conditions.'
For subscription services, test the cancellation path in advance at sign-up.
If damage occurs, use Consumer24, the Korea Consumer Agency, and the Fair Trade Commission reporting channels.

Latest Trends

The biggest change in 2024–2025 is the combination of AI-generated content and dark patterns. As virtual models, virtual reviews, and deepfake recommendation videos made with generative AI are distributed as if they were real people, it has become difficult to respond with existing regulation of 'verifiable falsehood' alone. Countries are moving toward introducing disclosure obligations for AI-generated advertising (the transparency provisions of the EU AI Act and discussions on Korea's AI Framework Act). In addition, problems continue regarding recommendation algorithms trained on synthetic data repeatedly exposing high-risk advertising to vulnerable consumers, strengthened enforcement of compensation disclosure in influencers' group buying, and legislative attempts to codify 'dark patterns' as unfair practices. The focus of regulation is also shifting from ex post punishment to ethical requirements at the design stage (privacy by design, prohibition of dark patterns by design).
