What Happens If Someone Posts False Accusations About You Online?
False online accusations that damage your reputation may constitute defamation (libel) under English law. The Defamation Act 2013 introduced a 'serious harm' threshold and important new defences.
Quick Answer
If someone publishes false accusations about you online and those statements have caused or are likely to cause serious harm to your reputation, you may have a claim for libel under the Defamation Act 2013. You can seek the removal of the content, compensation, and a court declaration that the statement was false. Legal action requires evidence of publication, falsity, and serious harm.
Full Explanation
Online defamation is governed by the Defamation Act 2013, which made significant changes to English libel law designed to protect freedom of expression while maintaining protection for genuine reputational harm. Under the Act, a claimant must show: (1) that a statement was published to a third party; (2) that the statement referred to them; (3) that the statement is defamatory in the sense that it would tend to lower them in the estimation of reasonable people; and (4) crucially, that the publication has caused or is likely to cause 'serious harm' to their reputation.
The serious harm threshold was introduced to discourage trivial and oppressive libel claims. For individuals, this requires demonstrating genuine reputational damage — not just embarrassment or hurt feelings. For companies, the harm must be serious financial loss. Courts assess this by reference to the number of people who read or engaged with the statement, its nature, and evidence of actual consequences.
Important defences are available to defendants: truth (the statement is substantially true — but the burden is on the defendant to prove this); honest opinion (a comment on a matter of public interest, based on stated facts, that a reasonable person could hold); and public interest (the publisher reasonably believed publishing was in the public interest).
Practically, before bringing a court claim, you should: send a 'Letter of Claim' to the publisher asking for removal and an apology; request removal directly from the platform (using the platform's reporting tools or a formal legal take-down notice); and consider whether an injunction preventing further publication is needed in urgent cases. The Defamation Act 2013 also provides a 'single publication rule' — you must bring a claim within one year of the first publication, not each time the content is accessed.
For social media platforms, you may report content to the platform under their community standards policies. Under the Online Safety Act 2023, platforms have enhanced duties to remove illegal content including false communications intended to cause harm.

What To Do
Preserve the Evidence
Screenshot the posts, pages, or videos with timestamps and URLs. Note the number of views, shares, and comments. This evidence will be essential for any legal action or take-down request. Use a tool or service that creates a verified record if possible.
Report the Content to the Platform
Use the platform's reporting tools to report the content as defamatory, harassing, or in breach of community standards. For major platforms, defamatory content against identifiable individuals can often be removed quickly, especially if you can demonstrate it is clearly false.
Send a Letter of Claim
If the poster is identifiable, send a Letter of Claim (using the Practice Direction on Pre-Action Conduct in Defamation) requesting: removal of the content; an apology; and a statement of what remedies you seek. Give 14 days to respond.
Apply for a Disclosure Order if the Poster Is Anonymous
If the defamer is anonymous, you can apply to the court for a Norwich Pharmacal order requiring the platform to disclose the identity of the poster. This requires evidence of a serious wrong and that disclosure is proportionate.
Issue Court Proceedings
If the content is not removed and the poster does not apologise, issue defamation proceedings in the King's Bench Division of the High Court (libel claims usually require the High Court for damages claims). Consider also whether damages or injunctive relief is your primary goal.
Important Deadlines
Important Warnings
Defamation claims are expensive and risk costs being awarded against you if you lose — always assess the likely outcome with a specialist media law solicitor before issuing proceedings.
The one-year limitation period from the date of first publication is strictly applied — do not delay.
Truth is an absolute defence to defamation — consider whether the person could prove the statements are substantially true before bringing proceedings.
