Social media has transformed defamation risk in Thailand. What was once limited to newspapers and television now extends to every Facebook post, LINE message, Instagram story, TikTok video, and Google review. A single online statement can trigger multiple criminal charges under different statutes. The penalties can reach ten years or more in prison.
This guide explains how Thailand’s defamation laws apply to digital content. It covers the Computer Crime Act, platform-specific risks, the charge stacking problem, and practical steps to protect yourself online.

1. The Digital Amplification of Defamation Risk
Section 328 of the Thai Criminal Code defines defamation by “publication” broadly. Thai courts have confirmed that social media posts qualify as publication under this section. The Supreme Court ruled in Decision No. 626/2563 (2020) that Facebook posts constitute “publication” and attract the harsher penalties of up to two years’ imprisonment and 200,000 Baht in fines.
The reach and permanence of social media posts create particular challenges. Courts have ruled that sharing or commenting on potentially defamatory content can constitute a separate act of publication. Screenshots of posts serve as evidence years later. Deleted content often remains recoverable through digital forensics.
A single post can reach thousands or even millions of people. This greatly increases the exposure to defamation claims compared to a private conversation. The legal consequences are proportionally more severe.
2. The Computer Crime Act: Sections 14 and 16
The Original Act: B.E. 2550 (2007)
The Computer Crime Act B.E. 2550 was enacted in 2007 to address cybercrime. However, it was quickly adopted as an additional tool for prosecuting online defamation. The Act creates criminal liability that runs parallel to the Criminal Code defamation provisions.
Section 14(1): False Computer Data
Section 14(1) criminalises the dishonest or deceitful entry of false or forged data into a computer system in a manner likely to cause damage to a third party or the public. The penalty is imprisonment of up to five years and/or a fine of up to 100,000 Baht.
Section 14(2): False Data Affecting National Security
Section 14(2) deals with false data that harms national security, public safety, economic security, or public infrastructure. The penalties are harsher: up to five years’ imprisonment and fines of 100,000 Baht.
Section 16: Defamation by Image
Section 16 targets the uploading of a person’s image into a computer system where the image was created, edited, or manipulated in a way that causes defamation. The penalty is imprisonment of up to three years and/or a fine of up to 60,000 Baht. This covers doctored photos, memes, and manipulated visual content.
The 2017 Amendment: Act (No. 2) B.E. 2560
The Computer Crime Act underwent major revisions in 2017. The amendments broadened the scope of the original Act and strengthened enforcement powers. They included enhancement provisions that can multiply prison sentences by up to ten or twenty times for aggravated offences. The amendment was adopted on 16 December 2016, published in the Royal Gazette on 24 January 2017, and became effective on 24 May 2017.
The Act requires “ill or fraudulent intent.” This offers some theoretical protection. However, prosecutors often argue that sharing false information demonstrates the required intent.
3. The Charge Stacking Problem
One of the most concerning features of Thai online defamation law is charge stacking. Prosecutors can bring multiple charges under different statutes for a single online post. A person who posts a defamatory comment on Facebook could face:
- Criminal Code Section 328: defamation by publication (up to 2 years)
- Computer Crime Act Section 14(1): false computer data (up to 5 years)
- Computer Crime Act Section 16: defamation by image, if photos are involved (up to 3 years)
The theoretical maximum exposure for a single social media post can reach ten years or more. This stacking practice creates enormous legal pressure on defendants. It is frequently used to force settlements or guilty pleas.
Before the 2017 amendment, the Computer Crime Act was already used to compound penalties alongside criminal law charges. The 2017 changes made this practice even more potent.
4. Platform-Specific Risks in Thailand
Facebook dominates Thai social media with 95% usage among enterprises. It is the primary target for defamation prosecutions. Public posts, comments on others’ posts, and content shared within groups have all led to criminal charges. The Supreme Court has explicitly confirmed that Facebook posts constitute “publication” under Section 328.
LINE
LINE is Thailand’s most popular messaging platform. Many users assume that private messages on LINE are safe. This is incorrect. Private conversations can be shared with others by recipients. Shared screenshots of LINE messages are routinely admitted as evidence in court. Group chats with multiple participants clearly constitute communication “before a third person” under Section 326.
Instagram, TikTok, and YouTube
Visual platforms carry additional risk under Computer Crime Act Section 16. Manipulated images, video commentary about identifiable individuals, and even captions accompanying photos can all trigger defamation and CCA charges. Content creators with large followings face heightened scrutiny because the potential reputational damage is greater.
Google Reviews and TripAdvisor
Negative business reviews are a growing source of defamation complaints. Even factual complaints can constitute defamation if they damage a business’s reputation. Review platforms do not provide immunity under Thai law.
5. The 24-Hour Takedown Obligation
Thailand’s 24-hour takedown obligation requires social media platforms to remove specified content within 24 hours of government notification. This creates pressure on platforms to proactively monitor and remove potentially defamatory content.
The takedown regime gives authorities rapid response capabilities. It also means that content you post can be flagged and removed very quickly. However, removal does not prevent criminal prosecution. Even if the content is taken down, the original posting can still form the basis of a defamation charge.
6. Strategic Litigation and Forum Shopping
The Computer Crime Act allows complaints to be filed in any jurisdiction where the content can be accessed. Since online content is accessible everywhere in Thailand, complainants can choose which police station or court to file in. This creates opportunities for “forum shopping.”
Complainants sometimes file in provinces far from the defendant’s home. This forces the defendant to travel long distances for legal proceedings. The tactic is used strategically to increase the financial and logistical burden on defendants.
Environmental activist Suraphan Rujichaiwat faced CCA charges filed in multiple provinces, including Phuket, despite living in northern Thailand. This illustrates how forum shopping can be used to harass defendants through Thailand’s legal system.
7. Intermediary Liability for Platforms and ISPs
Internet service providers and platform operators face liability under the Computer Crime Act if they fail to remove defamatory content after receiving notice. The 2017 amendments strengthened government powers to order content removal and website blocking. Non-compliance carries separate penalties.
This means that platform operators in Thailand have strong incentives to comply with takedown requests. It also means that content may be removed without the poster receiving notice or having an opportunity to respond.
8. Digital Evidence in Defamation Cases
Digital evidence plays a central role in online defamation cases. Thai courts accept screenshots, chat logs, website archives, and digital forensics reports. Deleted content is often recoverable. Metadata including timestamps, IP addresses, and device information can be used to identify the author of anonymous posts.
The Thai government has established specialised cybercrime units that actively monitor social media. These units have technical capabilities to track online content and identify its authors. The police Technology Crime Suppression Division (TCSD) handles many digital defamation investigations.
9. Social Media Best Practices to Avoid Defamation
Expatriates and businesses operating in Thailand should adopt defensive social media practices:
- Review before posting: Consider the potential reputational impact on any individual or organisation mentioned. Avoid naming specific people in negative contexts.
- Restrict privacy settings: Limit post visibility. Remember that “private” posts can become evidence if recipients share them.
- Document your sources: Keep records of facts and sources for any claims you make online. The burden of proof falls on defendants to demonstrate truthfulness and good faith.
- Avoid speculation: Do not share unverified claims. Phrases like “allegedly” or “in my opinion” provide little legal protection under Thai law.
- Understand cultural context: Comments acceptable in Western countries may be defamatory under Thai standards. Avoid discussions of the monarchy, senior government officials, or sensitive political topics.
- Never share or retweet without caution: Sharing defamatory content is treated as a separate act of publication. You can be charged independently from the original author.

10. Business Reviews and Consumer Complaints
Negative online reviews are a growing source of defamation complaints in Thailand. Reviews on Google, TripAdvisor, Facebook, and dedicated review sites can all trigger charges.
If you have a legitimate complaint about a business, protect yourself by:
- Confining your statement to provable facts.
- Avoiding emotional language or personal attacks.
- Considering official complaint channels before going public.
- Keeping evidence of your experience (receipts, photos, correspondence).
Businesses should also understand how to use and defend against defamation claims. See our guide on fraud and scam laws for related protections.
11. Frequently Asked Questions
Can I be charged for a private LINE message?
Yes, if the message is shared with a third party by the recipient. Group chats with multiple participants also constitute communication “before a third person” under Section 326.
Can deleted social media posts still lead to charges?
Yes. Deleted content is often recoverable through digital forensics. Screenshots taken before deletion are routinely admitted as evidence. Removing the post does not eliminate liability.
Does the Computer Crime Act apply to foreigners?
Yes. The Computer Crime Act applies to anyone whose content is accessible in Thailand. This includes content created and posted from outside the country.
Can I be charged for liking or sharing someone else’s post?
Sharing is clearly treated as a separate act of publication. Liking alone is a grey area, but Thai law is interpreted broadly. The safest approach is to avoid engaging with potentially defamatory content.
What should I do if I receive a defamation complaint for an online post?
Engage qualified Thai legal counsel immediately. Do not make additional public statements about the matter. Preserve all evidence. See our practical guide for foreigners for detailed emergency protocols.
