Social media can be a major growth channel for small businesses. It’s where customers discover you, check reviews, ask questions, and decide whether you’re trustworthy.
But the flip side is that social media can also be where things go wrong quickly - a negative post, a heated comment thread, a “warning” in a local community group, or a one-star review that crosses the line from criticism into something legally risky.
If you’re dealing with defamation on social media, you’re probably asking practical questions: Can I remove it? Should I respond? Is it worth taking legal action? Could my business be liable if someone comments on our page?
Below, we’ll walk through how defamation on social media works in Australia (from a small business perspective), what your risks are, and the steps you can take to protect your reputation without accidentally making the situation worse.
In simple terms, defamation is when someone publishes material that harms another person’s (or business’s) reputation.
On social media, “publication” is broad. It can include:
- a post on a business page or in a community group
- a comment under a post
- a story, reel, or video
- a review
- a “share” of someone else’s post (even if you didn’t write the original words)
- a DM where it’s communicated to someone other than the person or business it’s about (because publication generally involves communicating to at least one third party)
Critically, not every negative comment is defamation. Customers are generally allowed to share their opinion and experiences - including harsh ones. For small businesses, the difficult part is spotting when a post crosses the line.
Common Examples Of “Normal” (Non-Defamatory) Content
- “I waited 45 minutes and my order was cold.”
- “I wouldn’t go back - customer service was rude.”
- “This place is overpriced for what you get.”
These may be frustrating (and sometimes unfair), but they’re typically framed as personal experience or opinion.
Examples That May Raise Defamation Concerns
- accusing your business of criminal conduct (e.g. theft, fraud) without evidence
- alleging you’re “scamming customers” or “running an illegal business”
- claiming you “tamper with products” or “sell unsafe goods” with no factual basis
- making personal attacks against the owner or staff that could seriously harm reputation
Defamation law can be complex, and outcomes depend on context, wording, and what can be proved. But as a practical rule, the more the content asserts serious “facts” (rather than opinion) and the more reputational damage it’s likely to cause, the more legal risk it can carry.
Defamation law in Australia is mainly governed by state and territory legislation (which is largely uniform). While the details can vary, the core questions tend to be similar.
Generally, your business will look at whether:
- the content identifies your business (directly or indirectly)
- it was published to at least one other person (a post, comment, review, or share usually satisfies this)
- it carries a defamatory meaning (i.e. it would lower your reputation in the eyes of ordinary people)
- it has caused, or is likely to cause, serious harm (this “serious harm” concept is an important threshold in modern defamation law)
Also, not every business can sue for defamation. The rules around who can bring a claim can be technical. For example, in many cases excluded corporations (often smaller companies) may be able to sue, while larger corporations may not. Where the business owner’s personal reputation is targeted, sometimes the owner (as an individual) may be the correct claimant rather than the company.
Because these thresholds matter, it’s often worth getting legal advice early before spending time (and stress) escalating the dispute.
Defamation Vs Other Legal Issues (That Often Look Similar)
Sometimes what feels like defamation is actually better handled under a different legal pathway - or alongside defamation concerns.
For example:
In real life, one situation can involve several legal issues - and choosing the right approach can change the outcome.
Can Your Business Be Liable For Defamation On Your Social Media Page?
This is a big concern for small businesses, especially if your marketing relies on community engagement.
The short answer is: yes, it’s possible for a business to face legal risk if defamatory content is published through its page or channels - even where you didn’t write the original words.
Why? Because “publication” is not limited to the person who first typed the post. Depending on the facts (and noting this area has evolved through case law and reforms), risk can arise if you:
- repost or share defamatory content
- quote defamatory content in a way that repeats it
- encourage others to post damaging claims
- leave up defamatory comments on your page after becoming aware of them (this is highly fact-dependent, but it’s one reason having a moderation process matters)
What About Employee Posts?
If an employee posts something defamatory as part of their job (for example, posting from the business account, or responding to a customer as an “official” representative), your business may be exposed to risk.
This is why it’s worth having clear boundaries around who can post, who can respond, and what tone is acceptable - especially when someone is upset, stressed, or tempted to “clap back” publicly.
Even a well-meaning response can create problems if it escalates the allegations or includes personal information about the customer. If you need to communicate expectations clearly, a tailored employment contract and workplace policies are often part of good risk management.
How To Respond To A Potentially Defamatory Post Without Making It Worse
When your reputation is under attack, it’s normal to want to respond immediately. But with defamation on social media, speed can be your enemy if it leads to reactive messaging, admissions, or a reply that republishes the allegation.
Here’s a practical, small-business-friendly approach.
1. Take Screenshots And Preserve Evidence
Before you report or request removal, capture:
- screenshots of the post/comment/review
- the URL link (if available)
- the date and time
- any relevant replies, shares, or comments
Content can be deleted quickly, and you may need a record of what was said, where, and by whom.
2. Assess Whether The Post Is Opinion Or A Serious Allegation Of Fact
Ask yourself:
- Is this a customer describing their experience (even if unfair)?
- Or are they stating “facts” that accuse the business of dishonesty, criminal behaviour, or other serious misconduct?
- Could this meaning seriously harm the business’s reputation if left unaddressed?
This step helps you decide whether to take a customer service approach, a platform reporting approach, or a legal approach.
Small businesses are often tempted to respond with private details to “prove” the customer is wrong.
That can backfire fast. Even if you’re frustrated, disclosing customer details (bookings, invoices, addresses, medical or sensitive information, CCTV stills, etc.) can create privacy complaints, regulatory issues, and reputational damage.
If you want to respond publicly, keep it short, neutral, and focused on resolution. For example:
- invite the person to contact you directly
- confirm you take feedback seriously
- avoid repeating the allegation verbatim
Most platforms have reporting processes for harassment, hate speech, impersonation, and sometimes false information. While platforms don’t always move quickly, it’s still worth using these tools.
If the comment is on your page, you may be able to hide it (so others can’t see it) while you decide next steps. This can reduce the spread of harm.
Where the content is seriously damaging, a more formal approach may be appropriate - for example, a carefully drafted letter requesting removal, retraction, and an undertaking not to republish.
In some situations, a cease and desist letter can be a practical early step to stop the damage and create a clear paper trail.
It’s important that any written demand is accurate and well-pitched. Overly aggressive threats can inflame the situation, and poorly worded statements can create their own risks.
Practical Ways To Protect Your Business Reputation Before A Defamation Issue Happens
The best time to prepare for defamation on social media is before you’re in a crisis. A little planning goes a long way when things get heated online.
Set Up Internal Rules For Who Can Post And Respond
If you have staff (or contractors) handling social media, set a simple internal process covering:
- who can post from the business account
- who can reply to complaints
- when to escalate to a manager or owner
- what you will never post publicly (e.g. personal customer details, medical information, accusations)
This is particularly useful in industries where reviews and customer complaints are common (hospitality, trades, health, beauty, retail, eCommerce).
You don’t need to host abuse on your page. A basic moderation policy can make it clear that you’ll remove comments that:
- are abusive, threatening, or discriminatory
- contain personal information
- make serious allegations without evidence
- are spam or impersonation
Consistency matters. If you only remove some comments (or only those you disagree with), people may accuse your business of censorship or unfairness - which becomes its own PR issue.
Train Your Team On “Do Not Escalate” Responses
Many defamation disputes become worse because the business responds in anger. The response may:
- repeat the defamatory claim (spreading it further)
- add new allegations about the customer
- prompt a pile-on in comments
A short, calm response can protect your reputation better than a detailed argument.
Review Your Website And Public-Facing Communications
Defamation disputes often spill across channels: website testimonials, email newsletters, and marketing content.
It can help to ensure your outward communications are consistent and professional, particularly where staff are communicating publicly (or semi-publicly) about customers, complaints, or disputes.
Key Takeaways

- Your business can face risk if it republishes defamatory content or mishandles comments on your page, so moderation and response processes matter.
- If a post may be defamatory, preserve evidence first, avoid reactive replies, and consider platform reporting or a formal takedown approach where needed.
