Libel vs. Slander in the UK Explained for Social Media Disputes

Protecting Your Reputation on Social Media

Online arguments now move faster than most people can keep up with. A single angry post, short video or story can spread across platforms in minutes, and strangers can be sharing views about you or your business before you even see the original comment. Recent high-profile spats between creators, brands and commentators have shown how quickly reputations can be damaged when serious allegations are made online.

Understanding libel vs slander in the UK is not just for journalists and celebrities. It matters for anyone who posts, comments or shares content, from small businesses and influencers to employees chatting in group chats. At Lawdit, from our offices in Southampton and the Isle of Wight, we regularly advise on online defamation and intellectual property disputes, so we see the problems that can grow from one careless post.

This guide explains how libel and slander work in UK law and how they apply to social media posts, comments, reviews, videos and live chats on platforms like X, Facebook, TikTok, Instagram and LinkedIn. The aim is to help you protect your reputation, and avoid putting yourself at risk, when using social media.

Libel vs Slander in the UK Explained

Defamation is the legal term for a false statement that causes, or is likely to cause, serious harm to someone’s reputation. The law looks at how an ordinary, reasonable person would read or hear the words, and what they would think of the target as a result.

In the UK, defamation is split into two main types:

• Libel is defamation in a permanent form. That usually means written words, but it also covers recorded content, such as:
  •   Social media posts and comments  
  •   Blogs and online articles  
  •   Images with words on them  
  •   Recorded videos and livestreams that can be replayed  
  •   Emails, messages and DMs that can be saved  

• Slander is defamation in a transient, spoken form. Typical examples include:
  •   A spoken remark in a meeting  
  •   A phone call with no recording  
  •   A live audio chat with no recording or transcript  

Because social media content is usually written or recorded, most online disputes are treated as libel, not slander. Even content that feels temporary, like stories that disappear after a short period, can often be saved or screenshotted, which points towards libel.

For both libel and slander, the Defamation Act 2013 brings in a serious harm test. The claimant must show the statement caused, or is likely to cause, serious harm to their reputation. This is designed to filter out petty insults and minor online arguments, so the courts focus on more serious cases.

How Libel Applies to Posts, Stories and Livestreams

Social media makes it very easy to post first and think later. Some common situations that may amount to libel include:

• Accusing someone of a crime, fraud or serious misconduct without proof  
• Claiming a professional has behaved dishonestly or incompetently, in a way that could affect their job  
• Posting a negative review that makes false statements about a competitor’s products or services  
• Sharing or repeating someone else’s damaging post through quote tweets, reposts, stitches or duets  

To bring a libel claim about social media, a claimant normally has to show:

• Identification: That the words would be taken as referring to them, either by name, handle, image or description.  
• Publication: That the post was communicated to at least one other person.  
• Defamatory meaning: That the words would usually make people think less of them, avoid them, or treat them differently.  
• Serious harm: That the impact on reputation crosses the legal threshold, not just hurt feelings.  

Tensions can run high at certain times of year. For example, during spring, when businesses are launching new products, students are under exam stress, or professionals are dealing with the new tax year, people may be more likely to vent frustrations online. That can increase the risk of rash allegations being posted in the heat of the moment.

In online libel disputes, evidence is key. Helpful steps often include:

• Taking clear screenshots, including usernames, timestamps and comment threads  
• Saving URLs and any platform notifications you receive  
• Recording when you first saw the post and any reactions or replies to it  
• Keeping copies of any messages, emails or DMs linked to the dispute  

These records can help show what was said, when it was said, how widely it spread, and how it affected you.

When Spoken Words Become Slander in a Digital Age

While most online disputes are about libel, slander still exists in day-to-day life. Modern examples include:

• A defamatory remark made only during a private, unrecorded meeting  
• A phone call in which one person makes a false accusation about another  
• An off-the-cuff comment at a community event, heard by others but not recorded  

Digital platforms create some grey areas. Live audio rooms or gaming voice chats might be slander if nothing is recorded. But if the platform records the session, or if someone takes a recording, the same words may be treated as libel because they now exist in a permanent form.

In workplace and group chat settings, the line can be quite fine:

• A defamatory voice note in WhatsApp or Teams that can be replayed is likely to be classed as libel.  
• A one-off spoken remark during a meeting with no recording is more likely to be slander.  

Slander usually requires the claimant to show special damage, which normally means a specific financial loss, such as losing a job or a contract. There are limited situations where slander can be actionable without proof of financial loss, for example, some allegations of criminal behaviour or certain professional misconduct, but these scenarios are narrow and very fact-specific.

Defences, Free Speech and Safe Posting Online

Defamation law is not meant to stop free speech or fair comment. There are several key defences that may protect social media users, including:

• Truth: If the statement is substantially true, that can be a complete defence.  
• Honest opinion: If you express an opinion, based on true facts that you indicate, and a reasonable person could have held that opinion, this may protect you.  
• Publication on a matter of public interest: In some cases, sharing information on issues that affect the public may be defended if it was reasonable to publish it.  

Courts look at the whole context, including tone and style. Emojis, hashtags, memes and what some people think of as banter can all change how a reasonable reader understands a post. Saying something was a joke or sarcasm is not always enough if the overall impression is still harmful.

A few practical ways to keep yourself safer online include:

• Doing a quiet “spring clean” of your accounts, deleting old posts that worry you  
• Pausing before posting when you feel angry or stressed, and saving drafts to review later  
• Sticking closely to personal experience and clearly marking opinions as opinions  
• Avoiding sharing rumours or allegations you cannot back up  

If you realise you have posted something that may be defamatory, prompt action can limit the damage. Taking down the content, issuing a correction or apology where appropriate, and avoiding further comment can all be important, although what is best will depend on the specific situation.

Key Takeaways on Libel vs. Slander in the UK

• Libel is defamation in permanent form, slander is defamation in transient spoken form, and most social media disputes fall under libel.  
• The serious harm test under the Defamation Act 2013 is central to bringing a claim, especially for online disputes.  
• Recordings, screenshots and platform data can be decisive evidence in social media defamation cases.  
• Defences such as truth, honest opinion and public interest protect fair, fact-based commentary, reviews and complaints.  
• Early, specialist legal advice often helps prevent defamation disputes from escalating and can guide you on removal, rebuttal or litigation options.

FAQs on Libel, Slander, and Social Media Disputes

Q: Is a social media post always libel rather than slander?  

A: In most cases, yes, because posts, comments, stories and recorded videos are permanent or can be saved, so they are usually treated as libel. A purely live, unrecorded audio conversation on a platform could still amount to slander.

Q: Can I be sued for sharing or reposting someone else’s defamatory content?  

A: Yes. Reposting or sharing can count as publishing the statement again. Your own comments, the context and any defences that may apply will all be relevant, but simply saying you were only passing it on is not enough.

Q: What should I do if someone has defamed me on social media?  

A: Preserve evidence, such as screenshots, URLs, dates and any messages linked to the post. Avoid responding in anger, use the platform’s reporting tools where appropriate, and seek specialist legal advice as soon as you can.

Q: Are negative reviews about a business always defamatory?  

A: No. Genuine, fact-based reviews and honestly held opinions are usually protected. The risk arises when reviews contain false statements that are presented as facts, especially about dishonesty, safety or professional standards.

Q: How long do I have to bring a defamation claim in the UK?  

A: Generally, you have one year from the date of publication of the statement. Online publication can raise tricky questions about timing and repeat views, so it is important to get tailored legal advice promptly if you are concerned.
