Defamed on YouTube

Being defamed on YouTube is different from being defamed in a post. The allegation is spoken, often at length, sometimes over footage of your home or your business, and the comments underneath multiply it in writing. The Defamation Act 2009, as amended on 1 March 2026, treats all of that as publication. This guide sets out what a video is in law, who the possible defendants are, when the platform itself is drawn in, and the sequence from capture to court.

1. Defamed on YouTube: A Video Is a Statement

Section 6 of the Defamation Act 2009 defines the tort: a statement that tends to injure a person’s reputation in the eyes of reasonable members of society, published to at least one person other than the plaintiff, that identifies the plaintiff. “Statement” includes words, pictures, visual images, gestures and sounds, in any medium including electronic. A YouTube video is all of those at once. The words spoken to camera are a statement. The title and thumbnail are statements. A caption, an on-screen graphic, a gesture toward a photograph of you, a clip of your shopfront with a voiceover: each is a statement in its own right, published the moment one other person watches it. The 2009 Act abolished the separate torts of libel and slander, so nothing turns on whether the allegation was spoken or typed, and an individual does not have to prove financial loss.

Identification is the element people worry about when they are not named. A video that shows your face, your premises, your van or your handle identifies you as plainly as a name does. Gilroy v O’Leary [2025] IECA 42 is the Court of Appeal’s decision on YouTube publication, and it is cited here only as that: the reported authority on publication on the platform.

2. Three Possible Defendants

A YouTube video involves three parties who each publish something, and the claim has to be aimed with care.

• The channel owner is the author and the publisher of the video: they recorded it, uploaded it and chose the title. They are the usual defendant, against whom every remedy in the Act is available.
• The commenter who writes “I knew it, he did the same to my mother” under the video is the author and publisher of that comment, a separate statement, and is a defendant in their own right.
• The platform hosts the video but did not write it. Its position is governed by innocent publication under section 27, discussed below, which is why it is normally put on notice rather than sued first.

The practice page on online defamation and social media sets out the claim across every platform. The YouTube-specific points are the video format, the comment thread and the role of Google as host.

3. Capture the Video Before Anything Else

Evidence comes before the report, because a report that succeeds removes the very thing you need to prove. Record the URL and the upload date. Screen-record the video in full with the address bar visible, and note the timestamps at which each allegation is made, because a letter and a court will want the words quoted with the minute and second at which they are spoken. Note the channel handle and the view count on the day of capture. Screenshot the comments, expanding every reply thread, with usernames and dates visible. If the video has been shared elsewhere, capture that too. The date of first publication is the date the one-year clock under section 38 started, so it matters more than any other fact you record.

4. Report to YouTube and the Digital Services Act Route

With the evidence saved, report the video through the in-app process, citing defamation and, if the content fits, harassment. Keep the reference number and the date. The Digital Services Act, in force since 17 February 2024, requires platforms to run notice-and-action systems, so a notice identifying the video, the words complained of and the reason they are unlawful has to be processed and answered. Coimisiún na Meán is Ireland’s Digital Services Coordinator and enforces the Online Safety Code for video-sharing platforms. Two cautions. A platform report does not pause the limitation clock, and the platform decides on its own terms, which are not the Defamation Act. Removal through the report is a good outcome, but it is not a finding that the statement was false.

5. The Letter to the Channel Owner

Where the channel owner is known, a solicitor’s letter is the next step and often the last one. It quotes the words with their timestamps, states the meaning they carry, explains why they are false, and seeks removal of the video and the comments, a correction with the same or similar prominence as the original, an undertaking not to repeat the allegation, and an apology. The letter is quoted as a fixed sum after the consultation. The Act gives the channel owner two cheap exits that the letter should leave open: an apology under section 24, which is not an admission of liability, and an offer of amends under sections 22 and 23, which must be made before the defence is delivered. A letter that sets a deadline and names those exits resolves more matters than one that threatens.

6. When the Platform Is Joined: Section 27 and Notice

Section 27 gives a defence of innocent publication to a person who was not the author, editor or publisher of the statement and who took reasonable care in relation to its publication. YouTube is the obvious example. Before anyone has told it about the video, it has no knowledge of the words and reasonable care is easy to show. The point of the notice, whether the in-app report, the DSA notice or a solicitor’s letter addressed to Google’s Dublin entity, is that from that date the platform knows which video, which words and why they are said to be false, and its conduct after that date is what any question of reasonable care is measured against. In practice the platform is usually joined only where it has been notified, has not acted, and the channel owner cannot be identified, is outside the jurisdiction or has no means to meet an order. For most claims the channel owner is the defendant and the platform is the recipient of a notice.

7. Anonymous Channels and the Comment Thread: Section 45

Many channels that defame carry no real name, and most commenters post under a handle. Since 1 March 2026 section 45 lets the Circuit Court order an intermediary — a platform, host or provider — to disclose information identifying an anonymous author where the interests of justice require it, and the court may order the applicant to pay the intermediary’s costs. Before March 2026 this needed a High Court Norwich Pharmacal application. Google runs its European operations from Dublin, so the order is directed at a Dublin-registered company. The application is made on affidavit with the captured video, the handle, the reason the statement is false, the harm, and the steps already taken through the report process. The capture rules for disappearing content are in defamed on Instagram, TikTok or X. The one-year clock keeps running while the application is pending.

Comments are where a video does its lasting damage, because they turn one allegation into an apparent consensus. Each commenter is liable for their own statement under section 6, whatever the video said. A channel owner who leaves comments up after being notified of them raises the same question as the group administrator discussed in defamed on Facebook. The number of comments, like the view count, goes to the extent of publication under section 31 when damages are assessed; it does not change whether the statement was defamatory.

8. Remedies, Costs and the Clock

The Circuit Court, with its €75,000 jurisdiction in defamation, can grant a declaratory order under section 28 that the statement was false and defamatory, on a summary application and without damages; a correction order under section 30; and a prohibition order under section 33 against further publication where the statement is defamatory and the defendant has no defence reasonably likely to succeed. Damages under section 31 take account of the nature and gravity of the allegation, the means and extent of publication, any offer of amends or apology, and the plaintiff’s own evidence. Court proceedings carry a risk of being ordered to pay the other side’s costs if the claim fails, and most Circuit Court defamation claims settle before hearing. Before issuing, your solicitor must file the statutory declaration under section 34K on the ADR options.

Section 38 gives one year from the date of first publication, extendable to a maximum of two years only where the interests of justice require it, which the courts apply strictly. Section 11 gives one cause of action for all publications of the same statement, so the video staying online or gathering new views does not restart time. Work the dates through on the Defamation Time Limit Calculator before anything else is decided.

If you run a channel and have received a letter about a video, the same analysis applies from the other side: the elements of section 6, the defences of truth, honest opinion and fair and reasonable publication, and the offer of amends. We act for people who have been defamed and for people who have been accused of it, never for both sides of the same dispute.
