Analysis of LINE Account Suspension Reasons and Prevention Guide

As one of the most influential instant messaging applications in Asia, LINE has become the preferred platform for users in Japan, Taiwan, Thailand, and other regions due to its stable communication experience, diverse social ecosystem, and comprehensive privacy features. With the growth of cross-border e-commerce, overseas social media marketing, and international communication needs, more and more Chinese users are also starting to use LINE for communication, business promotion, or customer maintenance.

Factors that trigger LINE account bans

LINE’s risk control system comprehensively evaluates an account’s behavioral patterns, device fingerprints, and network IP addresses. If the behavioral characteristics do not match those of a “normal user,” the system is highly likely to automatically identify it as abnormal and trigger a ban. The following are common high-risk behavioral scenarios:

• Frequent IP switching or using public proxies : For example, logging in with a Taiwan IP today and switching to a US or Hong Kong IP tomorrow can easily be flagged as account theft or abnormal login.
• Abnormal account registration information : such as using a fake mobile phone number or virtual device to register, which will be identified as an “abnormal user” by the risk control system.
• Batch operations in a short period of time : including frantically adding friends, sending mass messages, modifying profiles, etc., will be classified as “robot operations” by the system.
• Accounts that are reported by users or violate content regulations , such as those involving sensitive or illegal information or being reported by multiple people, will also be directly banned.

Especially for users engaged in cross-border social marketing and e-commerce traffic generation, they are very vulnerable to being “caught” without proper network isolation and behavior control.

What are the signs that an account has been banned?

On the surface, a blocked LINE account doesn’t show any obvious changes; you can still open the app, view chat history, and even receive messages from friends. However, the true “ban” is silent—messages you send won’t actually be delivered; they’ll show as “unread” on your friends’ end, and you can no longer add friends or join groups. In this state, the account is essentially restricted from all external interaction, retaining only an “empty shell” interface, but it has effectively been isolated by the system.

How to properly appeal after an account is banned?

Detailed Explanation of the Official Appeal Channel

Once an account is banned, users need to submit an appeal form at the LINE official help center:

1. Enter LINE Customer Service Center
2. Select the appropriate issue category: “Account Issues → Account Blocked”
3. Fill in registration information and explain why your account was banned.
4. Waiting for official feedback within 3-7 business days.

Tips and precautions for a successful appeal

Key points: Ensure your appeal information is truthful and clear, especially specifying that the account did not violate any rules and that the device used was your own. If there were indeed previous violations, offer an apology and promise to correct them to increase the chances of your account being unblocked.

How can I fundamentally avoid having my account banned?

To truly reduce the risk of your LINE account being banned, it’s not as simple as “account nurturing”; you need to address both the account’s “behavior” and its “online environment.” Only when both meet the platform’s trust standards can the account potentially operate safely in the long term.

1. Simulate real user behavior to reduce suspicious operations.

• Do not perform a lot of actions immediately after registering an account, especially adding friends, sending mass messages, or frequently modifying information, as these are high-risk actions.
• Maintain a normal usage rhythm, such as adding only 1-2 friends per day and having genuine interactions with different users, to make the account seem more “human”.
• Set up a complete profile (avatar, nickname, bio) and participate in some real groups or activities to increase the “credibility” of your account.

2. Build a stable and realistic network environment

Many accounts are banned not because of behavioral issues, but because the online environment appears too suspicious:

• Using public proxy and data center IPs, with frequent IP changes.
• Log in to multiple accounts from the same IP address
• IP address does not match the country of registration.

The platform’s risk control system is not “reasonable”; it only judges whether an account is a “non-natural user” based on algorithms. Therefore, building a stable and authentic online environment is the core step in preventing account bans .

kookeey offers high-quality residential IP from 41 countries, with the following advantages:

• Static Residential Proxy : Real global home broadband IPs, stable account binding, reducing risk control risks.
• Dynamic Residential Proxy : Supports multiple IP pool switching methods, suitable for account testing and marketing scenarios.
• IP cleaning mechanism : Filters out “black IPs” and provides high-quality IP ranges for a cleaner and more secure IP environment.

By using them in a scientifically combined manner, this approach can both ensure account security and meet operational efficiency requirements, making it the most effective agency strategy for dealing with LINE’s risk control.
