All processors and subscription services, all processing services and maintain services directly affect corporate performance.In this process, you can obtain customer trust and create unnecessary departure, and create unnecessary departure.However, some companies apply design for short-term performance, and call it is called "Dark Pattern".In this article, I'll look at the major types of dark patterns of dark patterns to prepare.

1. Dark Patterns, Why Is It a Problem?

British designer Harry Bragnall first proposed the dark pattern in 2010, and it has now emerged as a worldwide consumer protection issue. The feature of this pattern is that it allows companies to act in the direction they want by using inconspicuous information or inadvertently overlooked psychology while using the service. It is especially difficult to notice the damage because it operates at moments when users are less likely to pay attention, such as right before payment or during the termination stage. Although this dark pattern can increase the conversion rate of purchases in the short term, it eventually increases customer dissatisfaction and reduces brand trust, leading to service disengagement. Furthermore, as the regulatory environment strengthens, companies can even face legal risks such as fines and fines. Now, dark patterns have become a threat to brand trust and legal responsibility at the same time, going beyond simple UX controversy.

2. E-commerce Act Revised in 2025, 6 Types of Dark Patterns

Although it appears to be a simple UX element, it actually distorts the user's choice to produce results that are favorable to the company in common with dark patterns. The following are the six main types specified by the Fair Trade Commission in the revised E-Commerce Act in February 2025.

① a hidden renewal
The free first-month trial will be offered, but will automatically be paid upon completion. It is commonly found in OTT, regular delivery services, and consumers will pay without clear guidance. Now, you must give at least 30 days' notice and get explicit consent from them.

② sequential disclosure pricing
It is a method of belatedly adding shipping or fees during the payment stage, even though advertisements offer a low price. It has been frequently pointed out as a problem on some global e-commerce platforms and accommodation and air reservation services, and is one of the most intensive types of crackdowns by the FTC.

③ Preselecting specific options
Options such as insurance, packaging, and donations are already checked in the payment box. If you proceed with the payment inadvertently, you will even pay unwanted expenses. In the future, items that are not selected by the consumer themselves cannot be automatically included.

④ Invalid hierarchy
The color, size, and position of the button are different to emphasize a specific option. For example, the 'Payment' button is noticeable and the 'Leave' button is hidden in small letters. This is a violation of the neutral design principle and is subject to regulation.

⑤ Interference with cancellation and withdrawal
Subscription is simple with one click, but it is designed to go through a number of complex steps. In the future, the subscription and cancellation process should have an equal level of convenience.

⑥ Repeated interference
The same request is repeatedly popped up even though the user refused. For example, a typical case is that a pop-up reappears a few days after refusing to receive an advertisement. Starting in 2025, repeating the same request is prohibited within at least seven days.


In Korea, the revised e-commerce law came into force in August 2025. Correction orders, fines, fines, and criminal charges are possible for violations of the dark pattern. The dark pattern is no longer a matter of choice, but an area directly targeted by regulation and law enforcement.

3. Effective Response Strategies for Dark Patterns

In a regulatory environment, businesses need a UX transformation strategy that goes beyond mere compliance and assets trust.

① UI/UX Improvements
The cancel and cancel buttons should be placed prominently and the advertising price should be matched with the final payment. The automatic selection of options should also be removed to encourage users to make their own choices.

② Recheck regular payment model
Customers must be informed at least 30 days in advance of price increases or paid conversions, and clear consent must be obtained. Rather than forcing customers to cancel, it is recommended to use a reasonable design, such as providing benefits when rejoining.

③ Establishing an internal inspection system
The marketing, design and legal teams should work together regularly to review UX designs and run internal processes that proactively filter out violations.

④ Leverage trust-based transformation strategies
The focus is on providing an experience that customers can feel they have chosen for themselves. For example, Platier "groobee" maintains a structure that optimizes the customer experience with personalized recommendations while still respecting the choice. As a result, we present an alternative approach to increase the conversion rate based on transparency and trust while excluding dark patterns.

Dark patterns can have short-term results, but they come at a high cost of service disruption and regulatory risk in the long run. Eventually, the era of UX design based on transparency and trust has begun to determine long-term competitiveness.
