Online defamation can damage a person’s reputation, reduce customer trust, and interfere with business relationships. A false review, social media post, video, or anonymous forum comment can be copied and redistributed before the target has time to respond.

The correct response is procedural: preserve the evidence, identify the policy violation, report the content, and consult counsel before sending threats or filing suit.

This guide provides general educational information. It is not legal advice, and Why Main Street is not a law firm, bank, financial advisor, or representative of any platform discussed here. Defamation law varies by state. Consult a licensed attorney before taking legal action.

What Online Defamation Is

Defamation generally involves four core elements:

1. A false statement of fact.
2. Publication of that statement to at least one third party.
3. Fault by the person who made or published it.
4. Harm to reputation or demonstrable economic injury.

A statement must generally be presented as fact rather than opinion. “I disliked the service” is usually opinion. “This company stole customer deposits,” if false and stated as fact, may present a different legal question.

Libel is written or recorded defamation. Online posts, reviews, articles, comments, images, and videos generally fall into this category.

Slander traditionally refers to spoken defamation. A livestream, podcast, voice message, or spoken video allegation may raise slander-related issues, although state law determines how the claim is classified.

Truth is generally a complete defense. Opinions, rhetorical exaggeration, satire, and statements protected by privilege may also be excluded. The target must establish more than offensive language or unfair criticism.

Section 230 Changes the Target of the Dispute

Section 230 of the Communications Decency Act generally provides that an interactive computer service is not treated as the publisher or speaker of information supplied by another content provider. The statutory text is available through Cornell Law School’s copy of 47 U.S.C. § 230.

In practical terms, the platform usually is not the primary legal target for a user’s defamatory post. The person or business that created and published the statement is usually the focus.

Section 230 also does not require a platform to remove every allegedly defamatory post. Platforms may voluntarily moderate content under their own rules, but they generally have no legal obligation to remove user content merely because someone claims it is defamatory. Revision Legal describes this distinction and notes that platform policies can still provide a basis for requesting removal.

Step 1: Document Everything Before Reporting

Do not begin by arguing with the poster. First preserve the record.

Capture full-page screenshots showing:

• The complete statement and surrounding context.
• The username, profile name, and profile photo.
• The platform and direct URL.
• The visible date and time.
• Comments, shares, reposts, views, and reactions.
• Any indication that the content was edited or removed.

Take separate screenshots of the account profile and the specific post. A cropped image without a URL or username may be difficult to authenticate later.

Save the original URL in a dated evidence log. Record the time zone. Download available videos, images, and attached files. Preserve original files without editing them.

For disappearing Stories, livestreams, temporary posts, or other ephemeral material, use a screen recording that captures the content as it appears. Record the account name and navigate to the content before it disappears. Preserve the recording’s original file metadata where possible.

Also collect evidence of harm:

• Lost customers or canceled orders.
• Rejected contracts or partnership discussions.
• Messages from customers citing the post.
• Changes in sales, traffic, or inquiries.
• Internal records contradicting the allegation.
• Sworn statements from witnesses who saw the content.

Store the evidence in at least two secure locations. Do not alter the original files. A lawyer or digital-forensics professional can advise on authentication, chain of custody, and preservation.

Step 2: Report the Actual Policy Violation

Platforms often respond more effectively to a specific policy violation than to a bare allegation of “defamation.” Select the category that accurately describes the conduct.

Possible categories include:

• Harassment or bullying.
• Impersonation.
• Fake reviews or conflicts of interest.
• Spam or coordinated manipulation.
• Privacy violations.
• Non-consensual intimate content.
• Threats or doxxing.
• Fraud or deceptive conduct.

X

On X, open the post menu, select Report Post, and choose the most accurate violation category. For fake accounts, report the profile for impersonation through X’s official impersonation reporting guidance.

Submit the direct post URL and explain the specific rule implicated. Avoid calling every negative comment defamatory. Identify the precise factual allegation and the evidence showing why it is false.

Facebook and Instagram

On Facebook or Instagram, use the post, comment, profile, or message menu and select Report. Choose harassment, bullying, impersonation, spam, or another applicable category.

For Instagram impersonation, Meta’s official instructions direct users to open the profile, select Report, choose Report account, and then select It’s pretending to be someone else.

For a business review, report the review itself rather than making a general complaint about the account.

LinkedIn

On LinkedIn, select the three-dot menu beside the post, comment, profile, or message. Choose Report or Report/Block, then select the category that best fits.

Business pages should preserve evidence of fake reviews, impersonation, and false claims involving employees or company representatives. Use LinkedIn’s help resources for reporting profiles when the content involves a fake account.

Google Business Profile

Google does not remove a review merely because it is negative. The review must violate a policy.

To report a review, open your Business Profile, select Read reviews, choose the review’s report icon, select the reason, and submit it. Google’s official review-reporting instructions identify examples such as spam and profanity and provide an appeal process.

Respond publicly only when appropriate. Use a professional statement such as: “We cannot locate a record matching this account, but we would like to investigate. Please contact us privately.” Do not disclose customer information or accuse the reviewer of criminal conduct without verified evidence.

Yelp

On Yelp, use the review’s options menu and select Report Review. Identify the specific guideline violation, such as a materially false factual claim, lack of firsthand experience, harassment, privacy disclosure, or conflict of interest.

Yelp also provides a Legal Content Removal Request process. Its guidance states that a final court order may support a later removal request. Yelp generally does not remove a review simply because the business dislikes it.

TikTok and YouTube

For TikTok, open the video, tap Share or press and hold the content, select Report, choose the reason, and submit. TikTok’s official instructions are available through its reporting help page.

On YouTube, use the video’s Report option or the three-dot menu beside a comment. Select harassment, impersonation, privacy, threats, or another applicable category. Preserve the video URL, channel name, publication date, and transcript before reporting.

Step 3: Consider Legal Escalation

If reporting fails or the harm is substantial, consult a defamation or internet-law attorney.

Possible options include:

Cease-and-Desist or Demand Letter

An attorney may send a formal letter identifying the false statements, demanding removal or correction, and instructing the poster to stop republishing them. A demand letter should be precise. It should not contain unsupported accusations or threats.

Cox Padmore Skolnik & Shakarchy LLP discusses business risk and online defamation concerns. The firm’s business-torts practice is another relevant reference point.

John Doe Lawsuit and Subpoenas

Anonymous posters cannot always be identified through ordinary requests. In some cases, a plaintiff files a lawsuit against a “John Doe” defendant and seeks a subpoena to the platform, host, or internet service provider.

Courts may require the plaintiff to establish a preliminary or prima facie showing of actionable defamation before ordering disclosure. Anonymous speech receives constitutional protection in some circumstances. An attorney must evaluate jurisdiction, procedure, and the evidence before filing.

Defamation Lawsuit

A lawsuit may seek compensatory damages, punitive damages where permitted, declaratory relief, or other remedies. The claimant must still prove the required elements, including falsity, publication, fault, and legally recognized harm.

Statutes of limitation are critical. Many states allow approximately one year for defamation claims; others allow two years or apply different rules. The clock may begin when the statement is first published. Do not assume that a continuing search result creates a new deadline.

Anti-SLAPP Risk

Many states have anti-SLAPP laws designed to dismiss lawsuits intended to silence speech on matters of public concern. A losing plaintiff may face expedited proceedings and attorney-fee exposure. The Reporters Committee for Freedom of the Press anti-SLAPP guide provides state-level background.

A lawsuit should not be used as retaliation against a truthful review or protected criticism. Counsel should assess falsity, public concern, damages, and applicable statutory protections first.

Step 4: Defend Your Reputation Without Amplifying the Attack

Do not quote the false claim repeatedly in posts, emails, or press releases. Repetition can increase its reach and search visibility.

Instead:

• Respond once, briefly, and factually when a response is necessary.
• Correct the record without naming or linking to the attacker unless counsel recommends it.
• Publish authoritative pages about your business, leadership, policies, products, and customer-service process.
• Maintain accurate profiles on relevant platforms.
• Encourage legitimate customers to provide honest feedback. Do not buy reviews or pressure customers to post specific language.
• Set up Google Alerts for your name, business name, products, and executives.
• Track search results, review platforms, and social mentions in a dated log.
