Korea Online Defamation Law Basics in One Glance

Want to understand Korea online defamation law? This guide explains it. One of the most confusing things foreigners face in Korea is this: a single review line or comment can start as a criminal case (police investigation), not a civil suit.

There are 3 key points:

• Defamation can apply even when the statement is true (exceptions exist separately) (Law.go.kr)
• Insults and slurs can also be punished as “insult” (Law.go.kr)
• Online speech can fall under the Information and Communications Network Act (Internet defamation), which may carry heavier penalties or fines (Law.go.kr)

Disclaimer: This article is a general information guide to help foreigners residing in Korea understand the Korea online defamation law and is NOT legal advice. If you face an actual case or receive a notice of complaint or investigation, consult a Korean lawyer or call the Foreigner Support Hotline (dial 1345, no area code).

Korea Online Defamation Law: 3 Categories Comparison Table

Category	What constitutes the offense	Statute / Penalty (summary)
Defamation (Criminal Act)	Publicly stating true facts or false facts that lower another person’s social reputation	True: up to 2 yrs imprisonment / KRW 5M fine; False: up to 5 yrs / KRW 10M fine (Law.go.kr)
Insult (Criminal Act)	Without asserting facts, publicly insulting through contempt, slurs, or profanity	Up to 1 yr imprisonment / KRW 2M fine (Law.go.kr)
Internet Defamation (Network Act)	On the internet or other information networks, with intent to defame, revealing true or false facts that damage reputation	True: up to 3 yrs / KRW 30M fine; False: up to 7 yrs / KRW 50M fine (Law.go.kr)

In practice, online posts and comments are usually charged under Article 70 of the Network Act (especially due to penalty severity), where the element of “intent to defame” becomes a separate issue. (Law.go.kr)

Korea Online Defamation Law: 3 Core Elements (Publicity, Identifiability, Expression Type)

Publicity: Did many people see it or could it spread?

The Supreme Court interprets the “publicity” element of defamation as a state in which an unspecified or large number of people can perceive it, and even when telling just one person, publicity can be satisfied if there is “potential for spreading”. (Law.go.kr) Related: 15 Must-Have Apps for Foreigners in Korea.

Insult similarly can satisfy publicity through “spreading potential,” but the Supreme Court holds that dolus eventualis (acceptance of the risk of spread) must be assessed carefully. (Law.go.kr) Related: How to Make Korean Friends — Complete Guide.

Practical translation (what foreigners actually feel). Related: Voice Phishing & Smishing Prevention Guide.

• Public SNS / online communities: publicity is almost always met
• Open chat / group chats: depending on member count and nature, publicity becomes contested (the key is “screenshot/forwarding potential”) (Law.go.kr)
• 1:1 DMs: if the recipient spreads it, it can still be an issue — never “fully safe” (case-by-case)

Identifiability: Risky even without a name if the person is recognizable

The Supreme Court holds that even without stating a name, when the content of the writing and surrounding circumstances together let people identify a specific person, the “identifiability” element can be satisfied. (Law.go.kr)

Risky examples (identifiable even without a name). For more, see the Korea Tourism Organization.

• “That Korean manager who works at ○○ club in Hongdae”
• “The foreign liaison in our company’s ○ team (title + department + incident)”

Expression Type: Stating Facts vs Emotional Reaction vs Value Judgment

• “He/she is a scammer / acted illegally” → likely read as fact (or a definitive assertion based on fact)
• “Really the worst / not great / unpleasant” → value judgment (but tone and context can still trigger disputes)

Why Truth Can Still Be Punished Under Korea Online Defamation Law

Criminal Act Article 310: Exemption when stating truth for public interest

Criminal Act Article 310 provides that if true facts were stated and solely for the public interest, then no punishment applies. (Law.go.kr)

The Supreme Court interprets this as:

• “True facts” means that the overall gist is consistent with objective facts in its main parts (some minor exaggeration is acceptable),
• “Public interest” includes not only the nation and society at large but also the interest of all members of a specific social group. (Law.go.kr)

The Supreme Court also recognizes that even if truth is not perfectly proven, if the writer believed it true and had reasonable grounds to do so, illegality may be excluded. (Law.go.kr)

However, “I believed it was true” alone does not grant automatic immunity — ultimately evidence, tone, purpose, and context are all weighed together.

Network Act Article 70: The “Intent to Defame” Element of Korea Online Defamation Law

Network Act Article 70 includes “intent to defame a person” as an element, and the Supreme Court holds that falsehood does not automatically establish defamatory intent, and the burden of proof lies with the prosecutor. (Law.go.kr)

Practical instinct

• Writing it as a “consumer warning / public interest” notice vs.
• writing it as “revenge / mockery / personal attack” carries vastly different risk (tone is decisive).

Korea Online Defamation Law: 10 Risky Expressions Foreigners Commonly Use

Below are words that carry strong legal meaning when used in Korean (definitive labels).

1. sagi (scam) / scammer / fraud
2. doduk (thief) / stole / theft
3. bulbeop (illegal) / illegal
4. Definitive sex-crime / school-violence / drug accusations
5. “100% confirmed,” “fact,” “I have evidence (but won’t share it)”
6. Real name + face + workplace/school/store info (= strengthens identifiability) (Law.go.kr)
7. Slurs and dehumanizing phrases like “this person is mental” or “crazy bitch”
8. Pointing at individual staff in reviews (“that female employee / that male manager”)
9. Profanity / mockery in KakaoTalk group chats (publicity issue) (Law.go.kr)
10. Unverified claims like “I reported to police / they’ll be arrested soon”

How to Reduce Korea Online Defamation Law Risk in Real Writing

Not a guarantee of immunity, but sentence structures that reduce dispute probability do exist.

Risky Sentences (Definitive Statements)

• “This store is a scam.”
• “The employee stole money.”
• “That person is an illegal overstayer.”

Relatively Safer Structure: Experience + Facts + Scope Limitation

• “Visited on 2026-01-10. The menu price and the charged amount differed, and an extra ○○ item appeared on the receipt. I asked for clarification but received no explanation.”
• “I felt that cash had gone missing from my wallet, and I requested CCTV review (result still pending).”
• “I cannot verify visa/status information, so I will not comment on it.”

Key points

• Definitive labels (criminal branding) replaced with observable facts as the main content
• Mention only what is verifiable (receipts, booking records, chat screenshots)
• Minimize personal info (face / real name / workplace / school) → lower identifiability risk (Law.go.kr)

Korea Online Defamation Law: 30-Second Pre-Post Checklist

Before hitting upload, check these:

• Does it include real name / face / phone / car plate / address personal info? (remove it)
• Are clues identifying a specific person (department, title, time, location) excessive? (Law.go.kr)
• Does it contain definitive legal labels like “scam / thief / illegal”? (rewrite as facts)
• Is my message in a channel likely to spread? (public community, group chat, etc.) (Law.go.kr)
• Can it be framed as “public interest” or does it read as “revenge / mockery”? (Law.go.kr)
• Have I secured evidence (receipts, bookings, chats, photos)?
• Have I first complained or requested a refund through official channels? (helps in disputes)

Korea Online Defamation Law Victims: How to Request Removal and Temporary Measures

See also Korea Stay Issues Resolution Guide and Foreign Resident Registration (ARC) Documents Guide.

When rights are violated online by defamation, you can request the platform to remove the content or post a rebuttal, and upon receiving such a request the operator must take necessary action — deletion or temporary measure — without delay and notify both the requester and the poster. (Law.go.kr)

Practical sequence (simple)

1. Secure the post URL / screenshot / author info
2. File the platform’s “rights violation / removal request”
3. Confirm whether temporary measures (access block) are applied
4. Consult police or legal counsel if needed

If a Complaint Is Filed: Minimum Response Principles for Foreigners

• “Ignoring” is the worst option (it can escalate to summons or investigation).
• Organize your original post + supporting evidence at the time of writing (receipts, chats, notes) in one folder
• Do not run a “defense campaign” via additional posts/comments (it only adds unfavorable sentences)
• If possible, consult a lawyer (with interpretation) to set direction
• Settlement / non-prosecution requests — understand the statutory structure

Note: under the Criminal Act, “insult” requires a complaint to prosecute (chingo), while defamation cannot be prosecuted against the explicit will of the victim. (Law.go.kr) Network Act defamation similarly cannot be prosecuted against the victim’s will. (Law.go.kr)

Korea Online Defamation Law FAQ

Q1. Can I be punished even if I wrote only the truth? A. Yes, it is possible. The Criminal Act exempts statements that are “true facts and solely for public interest,” and the Supreme Court has clarified the public-interest standard. (Law.go.kr)

Q2. Can KakaoTalk group chats trigger insult or defamation? A. Yes, depending on the case. The Supreme Court treats “spreading potential” as a key publicity criterion (for both defamation and insult). (Law.go.kr)
