In an era dominated by social media platforms such as Facebook, Instagram, and X (formerly Twitter), individuals frequently turn to these channels to share their views. However, many people mistakenly believe that expressing opinions online comes without legal consequences. This belief is misguided. South African defamation law applies equally to both online statements and those made through traditional media, and courts are increasingly confronted with the implications of defamatory digital content.
In South African jurisprudence, defamation involves the intentional and unlawful communication of a remark that tarnishes another person’s good name. When such content is disseminated via electronic platforms, it is referred to as cyber defamation.
Take, for example, the case of a fictional business owner in Johannesburg, John Doe. Following the dismissal of a former employee, Jane Smith, she took to Facebook with the following post:
“John Doe is a fraud! He rips off clients and abuses his staff. Avoid his business!”
The post quickly spread, with numerous users reacting, commenting, and even amplifying the post through shares and emojis. Reactions included symbols like flames and thumbs-up, and the comments section grew to include further unsubstantiated allegations. Jane continued adding claims in follow-up posts, further eroding John’s public standing.
The South African Constitution protects the right to freedom of expression under section 16, but this right is not unfettered. It must be weighed against other constitutional rights, such as the right to dignity under section 10. As highlighted by DP van der Merwe in Information and Communications Technology Law (2021), freedom of speech does not provide immunity for defamatory or malicious remarks.
A particularly important principle in defamation law is that individuals can be held liable not only for initiating harmful statements but also for endorsing or spreading them. This includes users who “like,” share, comment on, or otherwise engage with defamatory material in a manner that affirms or amplifies the harm. Even the use of certain emojis, depending on context, may be construed as supporting the defamatory message.
This concept was reinforced in the case of Isparta v Richter (2013), where the court found that a person who was tagged in a defamatory Facebook post and took no steps to distance themselves or remove the tag could be considered to have aligned with the defamatory sentiment. In Dutch Reformed Church Vergesig Johannesburg Congregation and Another v Sooknunan t/a Glory Divine World Ministries (2012), the court further ruled that a page administrator can be held liable for defamatory comments posted by third parties on their platform.
As for emojis, while they may appear innocuous, courts are increasingly considering their meaning in context. For instance, an angry face or alert symbol posted alongside defamatory claims may contribute to the overall defamatory nature of a thread, depending on how they reinforce the surrounding narrative.
In John’s case, the reputational fallout led him to seek legal relief. He applied for an interdict to compel the removal of the harmful content and stop any future defamatory posts. Although courts tread carefully when asked to limit expression, they are empowered to issue such orders where reputational harm is significant. John also initiated a damages claim, citing both reputational injury and business losses as a result of the viral accusations.
The evolution of online discourse demands a careful and informed approach from users. Whether through words, images, tags, or even emojis, participating in or amplifying defamatory content can expose individuals to serious legal consequences. It is increasingly important to exercise discretion and awareness in all forms of digital communication.
