Dark Patterns: Do Users Search for the Law or Coupang?

Typing the Same Words, Expecting Different Answers

On October 6, the Korea Fair Trade Commission (KFTC) released its “Guidelines for Operating Online Interfaces to Prevent Dark Patterns.” The document categorizes dark patterns into 13 types across 4 categories, detailing definitions, patterns of consumer harm, compliance requirements, and concrete examples for each. According to the KFTC, the release consolidates standards previously scattered across voluntary guidelines from 2023, a Q&A document from 2025, and amendments to consumer protection directives into a single reference.

When considering who actually reads this document, their questions split into two camps. One comes from those building the interfaces: “Does our current cancellation flow break the law?” The other comes from those on the receiving end: “Was that checkout pop-up I saw yesterday actually a dark pattern?”

Search data analyzed for this issue shows that “dark pattern” is searched nearly 2,000 times a month on average in Korea (as of August 2026). That represents a modest 5% increase over the comparison period—pointing to steady curiosity rather than a sudden spike. Yet search volume alone cannot tell us whether people were looking up statutory provisions or simply trying to put a name to an interface that frustrated them.

Traces of that second question appear far more clearly elsewhere. In early December 2025, right after a personal data leak at Coupang (Korea’s largest e-commerce platform), searches for “delete Coupang account” on Naver DataLab (a search trend tracker by Korea’s leading portal Naver) hit an all-time high, while media outlets covered user outrage over difficult cancellation flows using the term “dark pattern.” In this issue, I compare both questions against the same statutes and guidelines to trace where their answers diverge.

The Law Explicitly Bans Six Practices

Let us look at the statute first. Under the Electronic Commerce Act, amended in February 2024 and effective February 14, 2025, five practices in digital interface design are banned under Article 21-2, and one mandatory obligation concerning recurring billing is codified in Article 13, Paragraph 6. These six entries constitute what are widely referred to as the “six types of dark patterns.”

Category	Provision	Statutory Prohibition or Mandate	Exception
Drip Pricing	Article 21-2, Paragraph 1, Item 1	Luring users on the initial price-display screen by showing only a fraction of the mandatory total amount	Where justifiable grounds prevent showing the full total, and the omitted items and reasons are disclosed on the initial screen
Pre-selected Options	Article 21-2, Paragraph 1, Item 2	Pre-checking boxes during purchase or sign-up that opt the user into another product or service	None
Deceptive Hierarchy	Article 21-2, Paragraph 1, Item 3	Creating conspicuous disparities in size, shape, or color among options for purchase, sign-up, or cancellation, risking the false impression that only one choice is available or mandatory	None
Obstructing Cancellation or Account Deletion	Article 21-2, Paragraph 1, Item 4	Making cancellation more complicated than sign-up without justifiable grounds, or restricting cancellation to a different channel than the one used to enroll	Where justifiable grounds exist
Repeated Interference	Article 21-2, Paragraph 1, Item 5	Repeatedly prodding consumers through pop-ups or other prompts to alter a decision they have already made	When consumers are given the choice to suppress such prompts for at least 7 days
Hidden Renewal	Article 13, Paragraph 6	The obligation to obtain consent regarding timing, pre- and post-change pricing, and payment method at least 30 days before increasing recurring fees or converting free trials to paid tiers, while clearly disclosing cancellation terms and procedures	None

The law applies to electronic commerce operators and mail-order distributors¹. Nothing in the text of Article 21-2 narrows the scope by company size or industry vertical. A boutique online storefront and a subscription-based mobile app face the exact same legal bar. However, Article 13, which houses the hidden renewal provision, does not apply to securities, certain financial product transactions, or neighborhood retail transactions involving local daily necessities and food; nor does it apply to platforms brokering transactions strictly between non-business individuals (Article 3).

Violations trigger administrative fines². Under the Enforcement Decree schedule, penalties run ₩2,000,000 (~$1,440) for a 1st offense, ₩4,000,000 for a 2nd, and ₩10,000,000 for 3 or more offenses. Repeat counts tally identical sanctions incurred within the past 3 years. The statutory ceiling was originally ₩5,000,000 upon initial implementation, but an amendment passed in January this year and effective July 21 raised it to ₩10,000,000. Mitigating provisions also allow reductions of up to 70% for micro-enterprises exempt from mail-order distributor reporting requirements.

This answers the first operational question: “Does our UI violate the law?” If your interface lands in one of these six boxes, it violates the statute; if it does not, it is clear—at least under these specific provisions. Below is an article from Longblack (EP.9), a Korean business reading platform, in which I participated.

Seven of the Guideline’s 13 Categories Fall Outside These Six Boxes

The latest guideline reaches wider than those six boxes. According to a summary by law firm Cheongchul, the 13 categories break down as follows:

• Siphoning: Hidden renewal, drip pricing
• Misdirection: Pre-selected options, false hierarchy, fake discounts, fake endorsements, bait and switch, disguised advertising, trick questions
• Obstruction: Hindering cancellation or account deletion, hidden information, preventing price comparison
• Pressure: Repeated interference

The 2023 self-regulatory guideline contained 19 categories, of which only 6 had an explicit statutory basis. While the new version consolidates them into 13, the underlying structure remains similar. The 6 categories that the statute directly prohibits under administrative fines sit side by side in a single document with 7 that fall outside Article 21-2 and Article 13(6)—namely, fake discounts, fake endorsements, bait and switch, disguised advertising, trick questions, hidden information, and preventing price comparison. These outside 7 can still run afoul of other statutory provisions, but they travel a different path from the administrative fine regime governing the 6 designated dark-pattern categories. I have not been able to inspect the original text of the guideline to review how it maps each category to specific legal provisions.

The guideline itself carries no legal binding force. Whether a practice constitutes a violation is still judged against the E-Commerce Act, its Enforcement Decree, and the Consumer Protection Guidelines. Instead, this guideline lays out remarkably concrete benchmarks that practitioners can apply immediately. Synthesizing press reports and law firm analyses, the core takeaways look like this:

• Place cancellation and account deletion buttons within direct reach from the initial landing screen—such as the home dashboard or My Page—and do not hide them inside counterintuitive menus like “Edit Profile” or “Security Settings.”
• Label buttons so that their action is immediately obvious, using plain terms like “Cancel Membership” or “Delete Account.”
• Violations cited include allowing users to sign up online while restricting cancellation to phone calls, emails, in-person visits, chatbots, or 1:1 inquiry tickets; forcing users to complete surveys before cancelling; and deeming continued use as automatic consent to a price hike.
• As best practices, the guideline recommends giving recurring pop-ups an option like “Do not show again for 7 days” and designing consent and decline buttons in comparable sizes and colors.

From the perspective of those who design screens, this document answers the first question quite directly. From the user’s perspective, however, one caveat is essential: just because an interface fits one of these 13 categories does not mean it automatically violates the dark-pattern regulations.

Mapping Familiar “Coupang Dark Patterns” Back to the Law

Let’s turn to the second question. In Korea, the platform cited most frequently in discussions of dark patterns is Coupang. Yet three widely known episodes involving the company each traveled down entirely distinct legal paths.

The April 2024 Price-Hike Pop-Up

On October 15, 2025, the Korea Fair Trade Commission (KFTC) issued corrective orders and levied a combined ₩10.5 million (~$7,600) in administrative fines against 4 subscription services. Coupang’s share was ₩2.5 million (~$1,800). When the company raised its monthly WOW membership fee from ₩4,990 to ₩7,890 in April 2024, it ran into trouble with its in-app launch pop-up: the “Agree and Continue Benefits” button was displayed prominently in large blue at the bottom center, while the “Do It Later” option was relegated to the top right on a small white background. According to an analysis by the law firm Daeryun, the pop-up reappeared every 5 days even after tapping “Do It Later.” On the same day, local streaming platform Wavve (₩4 million) and music service NHN Bugs (₩3 million) were penalized for obstructing cancellations by failing to properly disclose immediate-refund cancellation procedures, while Spotify (₩1 million) faced penalties for omitting statutory cancellation terms and mandatory business information.

This enforcement action is frequently cited as the first penalty handed down under Korea’s dark pattern provisions. Look at the timeline, however, and Coupang’s pop-up took place 10 months before the 6 dark pattern categories officially went into effect. Daeryun points out that Coupang was sanctioned under the pre-existing prohibition against deceptive customer inducement (Article 21).³ If one were to evaluate that pop-up against today’s legal provisions, the stark differences in button size and color resemble an “asymmetric hierarchy”; reappearing every 5 days runs afoul of the 7-day threshold for “repeated interference”; and bundling recurring price-hike consent mimics “hidden renewal.” Naturally, any official determination rests solely with the KFTC.

The December 2025 Cancellation “Maze”

Following a massive personal data breach that triggered a wave of cancellation requests, a reporter from the domestic wire service Newsis attempted to cancel a WOW membership firsthand. Even after locating and clicking the cancellation button, the reporter had to navigate 7 to 8 successive screens promoting retention perks, Coupang Eats, and Coupang Play. The process concluded only after clicking a final prompt that read, “Forfeit WOW Exclusive Coupons.” According to reporting by Digital Daily, Coupang streamlined the membership cancellation process around December 12 into 2 stages—“Cancel” and “Complete Cancellation Request”—while trimming account deletion from 6 steps down to 4. The report cited intervention by authorities, including the Personal Information Protection Commission (PIPC), as the catalyst.

This episode generated the single largest spike in search traffic on the topic. Yet my reporting found no record of regulatory sanctions being handed down against this cancellation flow under the newly enacted dark pattern rules.

The June 2026 “WOW Member Price”

On June 9 of this year, the KFTC imposed an administrative surcharge of ₩500 million (~$360,000) on Coupang. The agency cited Coupang’s practice, between August 2020 and May 2022, of advertising prices that factored in a one-time onboarding coupon as if they were everyday, standard “WOW Member Prices.” Because calculating the exact relevant revenue proved difficult, regulators levied the statutory maximum fixed surcharge. In the vernacular of consumer guidelines, this tactic mirrors false discounts or hidden terms. The statute applied, however, was not the Electronic Commerce Act, but the Fair Labeling and Advertising Act.

In short, the three episodes collectively remembered by the public as “Coupang dark patterns” were handled through three entirely separate legal avenues: deceptive customer inducement, voluntary remediation prompted by regulatory scrutiny, and the Fair Labeling and Advertising Act. Not one of them was fined under the six specific dark pattern provisions that took effect in February 2025.

The Dark Pattern Rules Are Operating Without Names

Where, then, are the 6 dark pattern categories actually having an effect? A monitoring report released by the KFTC on September 30, 2025, offers a clue. During a sweep of major online business interfaces in the months immediately following enactment, the agency uncovered 45 suspected violations across 36 companies. Obstruction of cancellation and account deletion was the most frequent infraction with 15 cases, followed by 9 cases of hidden renewals and 6 cases of asymmetric hierarchies. Subscription services—including video streaming, music, and e-books—accounted for 16 cases on their own. Of the total, 34 infractions were resolved through voluntary remediation by the operators, while 11 submitted formal corrective action plans. Documented remediation examples included enabling direct cancellation within the same app or website used for signup, displaying the all-inclusive total price on the initial screen, and ending the practice of featuring child rates as default pricing for adult services.

The identities of those businesses were never made public. For that reason, the second question—“Was that frustrating interface I encountered an actual violation of the law?”—rarely comes with a brand-name answer. When consumers search by service name, they find headlines and grievances; the record of how the law actually functioned remains filed away as an anonymous tally of corrective actions.

Questions Left When Measuring Your Screens Against the Law

If you build user interfaces, you can turn these 6 areas into a checklist. The left column lists questions the statutory text answers with relative clarity, while the right highlights the gray zones where subjective judgment is still required.

Check Item	Questions Answered by the Law	Where Judgment Calls Remain
Price display	Are mandatory costs like shipping and service fees included in the initial screen price?	The scope of “justifiable grounds” for withholding the full amount
Add-on items during checkout	Are optional products or supplementary subscriptions pre-checked?	Virtually none. The statutory text is quite clear here
Agree vs. Decline buttons	Are the two buttons noticeably different in size, shape, or color?	The threshold where a difference becomes “substantial,” and when it creates a “risk of misleading users”
Cancellation & account deletion	Can users cancel using the same method they signed up with? Does cancellation take more steps than sign-up?	How many benefit-reminder screens or discount offers count as “overly complex design” before cancellation? The law specifies no exact number
Repeated pop-ups	Does the screen repeat a request the user already declined? Can they select “Do not show again for 7 days”?	The boundary between repeating the same request and introducing genuinely different perks
Recurring payment changes	Do you obtain consent at least 30 days before a price hike or transition to a paid plan?	The law does not explicitly dictate how to treat users who simply do not consent

Fill out the table, and you will see that the right column overlaps almost entirely with what genuinely frustrates consumers. The relentless barrage of benefit-reminder screens right before cancellation is the prime example. The 7 to 8 steps endured by a reporter from the Korean news agency Newsis fall squarely into that column. While enforcement guidelines cite clear-cut violations like mandatory exit surveys, they offer no magic number for how many retention offers a platform can display before crossing the line.

Oswarld’s Lens

If you design user interfaces, it is safer to treat those 6 steps as a hard floor. Under dark pattern regulations, the fine for a 1st offense is ₩2 million (~$1,450), and when the initial penalties were handed down, industry insiders even remarked that paying the fine was cheaper than redesigning the screens. Yet Coupang’s trajectory shows that the real costs came from outside this provision. The same company paid ₩500 million (~$360,000) under the Fair Labeling and Advertising Act, and its cancellation process was overhauled not by administrative fines, but under pressure from public backlash and regulatory scrutiny.

In this light, the 2 questions in the search bar run on entirely different clocks. The legal question takes time to deliberate whether conduct violates the statutory letter, and its resolution often remains anonymous. The user experience question, however, is already answered the moment a consumer pairs your service’s name with “cancel membership” in a search box. For practitioners, regardless of whether you clear those 6 steps, you are far better off counting how many times a user hesitates the 1st time they encounter your cancellation screen.

Closing

This guideline is ultimately designed to answer one specific question: “Does our interface break the law?” To the consumer’s question—“Was what I just ran into actually a dark pattern?”—it offers only a partial answer, filtered through where the behavior lands across those 6 boxes. And that answer points to a specific brand name far less often than you might expect.

Footnotes

1. Mail-order distributor (tongsin panmae-eopja): A business that sells goods or services non-face-to-face, such as through online shopping portals or mobile apps. While businesses below a certain transaction volume or threshold set by the Korea Fair Trade Commission (KFTC) are exempt from formal business reporting duties, they remain fully subject to the statutory prohibitions against dark patterns. ↩

2. Administrative fines (gwataeryo) and penalty surcharges (gwajinggeum): An administrative fine (gwataeryo) is a fixed-range financial penalty imposed for breaching administrative compliance duties. A penalty surcharge (gwajinggeum), by contrast, is designed to disgorge illicit profits generated by unlawful conduct and can reach substantially higher sums. Violations of the 6 dark pattern provisions incur administrative fines, whereas Coupang’s “WOW member price” case triggered penalty surcharges under the Fair Labeling and Advertising Act. ↩

3. Prohibition of deceptive inducement (Article 21 of the E-Commerce Act): A statutory clause prohibiting businesses from luring consumers or executing transactions through false claims, exaggerations, or deceptive tactics. Because this provision predates the codification of the 6 explicit dark pattern categories, regulators previously relied on it to sanction manipulative interface designs. ↩
