BEFORE YOU JOIN THE FACEBOOK BANDWAGON: A PRACTICAL NOTE ON DEFAMATION
Facebook is a forum for robust debate. It is not, however, a jurisdiction in which reputation has no protection, evidence has no consequence, and every accusation becomes lawful merely because it is described as an opinion.
Consider a purely fictional example.
“D”, an entirely fictional Facebook user, publishes an uninformed post in a Facebook group about another person.
The post contains serious factual allegations, colourful insults and conclusions drawn without first obtaining or examining the relevant evidence.
Other users then enter the discussion. Some repeat D’s allegations. Others embellish them, introduce new accusations or present speculation as established fact. A few share the post with approving commentary.
What began as one person’s publication may consequently become several legally distinct publications.
South African law does not treat a Facebook thread as an evidence free conversation. A person who authors, repeats, republishes or adopts defamatory matter may, depending on the precise words and surrounding circumstances, become responsible for their own publication.
That does not mean that every disagreement, criticism, reaction or “like” automatically creates liability. It means that each person’s conduct must be assessed individually, carefully and in context.
How should the person affected respond?
1. Do not litigate emotionally in the comments
Do not answer insult with insult.
Do not make retaliatory allegations.
Do not threaten every participant indiscriminately.
A measured silence while evidence is being preserved is not weakness. It is discipline.
2. Preserve the evidence before anything is deleted
Capture the original post and the entire discussion, including:
• the name and profile of the person publishing it,
• the group name and apparent audience,
• the exact words used,
• the date and time,
• the post’s direct internet address,
• all comments, shares and reactions,
• any edits or later deletions, and
• messages from people who saw or understood the publication.
Take full screenshots and a continuous screen recording showing the page being opened and scrolled.
Save copies in more than one secure location. Where the matter is serious, formal forensic preservation should be considered.
A cropped screenshot containing only an offensive sentence may omit the context that a court will need.
3. Build the case publication by publication
A properly prepared defamation matter is not framed as a vague complaint against “everyone on Facebook”.
A separate evidential record should be prepared for D and for every person who joined the discussion. That record should identify:
• what that person actually published,
• whether the person originated, repeated or added to an allegation,
• whether the words referred to the affected person, expressly or by implication,
• what an ordinary reasonable reader would probably understand the words to mean,
• to whom the statement was published,
• why any factual allegation is false or unsupported,
• what defence the publisher might raise, and
• what actual reputational harm followed.
This defendant by defendant approach distinguishes a properly constituted claim from an emotional response to online hostility.
4. Understand the difference between fact and comment
Calling an allegation an “opinion” does not automatically protect it.
A court considers the substance and context of the publication. A supposed question may carry a factual implication. An insinuation may be as damaging as a direct accusation.
Truth and public benefit may provide a defence. Fair or protected comment must be recognisable as comment and must rest upon substantially true facts that are properly indicated or known. Honest criticism is protected. Invented facts, reckless repetition and malicious embellishment are not converted into protected speech merely by adding “in my opinion”.
5. Record the harm
Keep evidence of clients, colleagues, family members or members of the public who encountered the publication. Preserve enquiries, cancellations, lost instructions and communications showing how readers understood it.
Reputational harm should be demonstrated by evidence wherever possible, not asserted only in general terms.
6. Seek proportionate relief
After the evidence has been secured, appropriate steps may include:
• reporting the material to Facebook,
• demanding removal of the offending publications,
• requesting a correction or retraction in the same forum,
• requiring an undertaking against repetition,
• seeking an apology,
• applying for interdictory relief where unlawful publication is continuing or credibly threatened, and
• instituting a properly pleaded action for damages where warranted.
Urgency and proportionality matter. Delay may weaken an urgent application, while an excessively broad demand may create unnecessary legal and reputational complications.
A final word to the prospective commenter
Before joining an online pile on, pause and ask:
Do I know this allegation to be true?
Can I identify the reliable facts upon which it rests?
Am I contributing genuine information, or merely amplifying someone else’s anger?
Would I be prepared to place the same allegation, with its supporting evidence, before a court?
The internet may make publication instantaneous. It does not make accountability disappear.
Freedom of expression protects debate, criticism and honestly held views. It does not confer a licence to manufacture facts, destroy reputations or turn collective indignation into collective irresponsibility.
“D” is a fictional character used solely to explain general legal principles.
