PRETORIA, 29 May 2026. Days after Africa Day passed in the shadow of boycotts and repatriations, South Africa is confronting an uncomfortable truth about the crisis unfolding within its own borders. On 25 May, the day the continent traditionally affirms its unity, African ambassadors refused to attend South Africa’s official celebrations, citing safety concerns. Nigeria and Ghana had already begun repatriating their citizens. At least seven people were dead. The movements behind the violence, March and March and Operation Dudula, swept through Johannesburg, Pretoria, and Durban, leaving fractured communities, destroyed businesses, and formal diplomatic complaints from Nigeria, Ghana, and Mozambique in their wake. A United Nations warning drew international headlines. The algorithm did not start this fire. But it is fanning it, and it will keep doing so until media algorithms are held accountable, communities are equipped to resist manipulation, and policymakers choose evidence over the applause of the crowd.
A country that presents itself as the gateway to Africa is being watched with alarm by the very neighbours it claims to lead. The answer to why this is happening now, and with such intensity, lies at the intersection of economic frustration, political orchestration, and a digital ecosystem engineered to reward outrage. South Africa’s 2022 census shows migrants make up just 3.9 percent of the population, roughly 2.4 million people in a nation of 62 million. The country is not being overrun. It is, however, in acute economic pain, and in the age of social media, pain travels fast.
Legitimate Grievances, Distorted by Design
The Centre of Artificial Intelligence for Sustainable Development www.caisd.africa , one of the many centres in the continent working to harness the role of technology to achieve development, pinpoint the role technology plays in exacerbating the antipathy without dismissing the frustrations of South African nationals. To do so would be dishonest and counterproductive. The official unemployment rate stood at 32.7 percent in the first quarter of 2026, with more than 8.1 million people without work and youth unemployment reaching a staggering 57 percent. These are lived realities in communities that have spent three decades waiting for economic transformation.
Against this backdrop, the visible economic presence of foreign nationals creates friction that is psychologically real, even where it is statistically misread. Statistics South Africa data shows that foreign nationals carry an employment absorption rate of 64 percent, compared to 37.7 percent for South African-born workers, and in some townships they own up to 40 percent of informal businesses. A 2025 Human Sciences Research Council survey found that 42 percent of South Africans would welcome no immigrants, while 77 percent agreed that immigrants increase crime. The crime link is not supported by evidence, but these numbers reveal something significant: a large portion of the population has already been persuaded by a narrative. The critical question is who built that narrative, and how was it distributed so effectively?
The Algorithm: Not the Cause, but the Accelerant
The social media platforms most South Africans use daily, including Facebook, TikTok, X, WhatsApp and YouTube, are not neutral infrastructure. They are built around a single commercial objective: sustained engagement. Decades of research, including internal studies from Meta, show consistently that the content most likely to sustain engagement is content that provokes anger.
Anger travels. A video of a foreign national behaving badly, stripped of context, spreads further and faster than any evidence-based article about what immigrants contribute to the economy. In the lead-up to the 2026 protests, populist leaders and influencers circulated incendiary content without context. Those videos were algorithmically rewarded with reach, shared into WhatsApp groups where factchecking is practically impossible, and broadcast live on platforms that amplified these movements before any journalist had assessed whether their claims were truthful.
Research on South African electoral cycles reveals a consistent and troubling correlation: xenophobic discourse spikes reliably in the approach to local elections, in 2016, 2019, 2020, and now 2026, with local government elections scheduled between November 2026 and January 2027. Xenowatch data confirms the trajectory, with recorded incidents rising from 58 in 2020 to a peak of 110 in 2022, before climbing again to 83 in 2024. The algorithm does not cause xenophobia. But it is extraordinarily effective at timing it, scaling it, and normalising it.
The Dark Labs: Organised Narrative Operations
Beyond algorithmic mechanics lies something more deliberate. There is growing evidence of what we at CAISD terms “coordinated narrative architecture”: the strategic seeding of divisive content by small, well-resourced operations, some functioning entirely outside South Africa. These are not spontaneous expressions of public anger. They are manufactured interventions, exploiting the fact that, if enough accounts share the same message within a narrow window, platforms will push it to audiences who were never searching for it.
This is a documented feature of contemporary information warfare, evidenced in Brexit, in the United States during the 2016 election cycle, and increasingly in African political contexts. When mainstream media then covers these movements without adequately challenging their claims, including the demonstrably false assertion that some youths purported to be undocumented migrants are not entitled to public healthcare and education under South African law, it lends those claims a credibility they do not deserve.
Evidence, Policy, and the Way Forward
The World Bank’s studies of South African labour markets have found that immigrants are net contributors to job creation. Foreign-owned enterprises sustain supply chains that employ South Africans. South Africa’s chronically low GDP growth of between 0.6 and 1.3 percent annually is a structural problem rooted in energy infrastructure failure, skills deficits, investor uncertainty, and governance weaknesses that predate every foreign-owned spaza shop in the country. Deporting 2.4 million people will not build a single power station, train one additional nurse, or resolve the Eskom crisis.
The government has a legitimate mandate to enforce immigration law, process permits efficiently and protect South African workers. What is far more troubling is when the tone of official policy pronouncements begins to track the mood of protests rather than the weight of evidence. That convergence, historically, is where crises cross thresholds they cannot easily come back from.
CAISD’s call is therefore clear. Social media platforms must be held accountable for algorithmic amplification of xenophobic content, including through multilingual content moderation. Digital literacy must become a civic priority. Counter-narratives must be deployed as strategically as the narratives they counter, because facts alone do not go viral, but stories do. And African governments and civil society must speak with one continental voice, because the diplomatic rupture South Africa is experiencing today is a warning of what silence costs the entire continent.
