CONCERNS are mounting that the open-edit nature of Wikipedia is increasingly being exploited to alter information in ways that could mislead millions of users, particularly those in digital and informational blind spots.
Wikipedia, the world’s largest free online encyclopedia, allows anyone with internet access to edit most of its articles.
While the platform was designed to democratise knowledge, evidence suggests that some pages are being systematically manipulated by individuals, political groups, and public relations firms seeking to shape narratives in their favour.
Investigations in recent years have uncovered coordinated editing campaigns in which networks of accounts made favourable changes to corporate or political profiles while removing critical information.
Public figures, institutions, and controversial organisations are especially vulnerable. Their biographies and histories can change dramatically within hours, depending on which editors are most active at a given time.
Although Wikipedia keeps a public revision history of all changes, few ordinary users check it before accepting what they read as accurate.
Stakes are particularly high in the Global South, where many people rely on Wikipedia as their primary source of information due to limited access to libraries, academic journals, or independent media. In countries with high data costs and restricted press environments, a single altered Wikipedia page can shape public perception with little scrutiny.
Case studies
This month, Arab-Israeli creator Nassir Yassin said that his Wikipedia has been hacked and locked by anonymous wiki-editors, leading to gross misinformation.
“In the last two years, 10 Wikipedia editors colluded to change my Wikipedia articles and make me look bad,” he says.
“Everything negative, they wrote, and everything positive, they deleted, and I have no control. The editors would like to paint me like another ‘bad Israeli’.”
“On Wikipedia, Nas Daily is hated. The welcome section is all negative because I have a normalising agenda. This means I am trying to make peace between Israelis and Palestinians, but they made it sound bad.
“They locked my Wikipedia, and now, I cannot make changes,” he says. “This is not only about me, but millions of articles have been manipulated already. If your kids use Wikipedia, they will be in trouble because they will never learn the truth.”
A decade-long investigation reveals systemic vulnerabilities after a fictional inventor, Alan MacMasters, was falsely credited with inventing the toaster.
Additional breaches include the 4,500-word Bicholim Conflict fabrication and a Scots Wikipedia scandal where an American teen authored 20,000 gibberish articles.
In Yassin’s video, which he published on his vlogging platform, Nas Daily, Wikipedia co-founder Larry Sanger said the platform has lost its way.
“Wikipedia has lost its way. It takes a definite stance on the issues that divide people by nationality, ideology, party, philosophy, religion, whereas in the first five years or so, they did not do that so much,” Sanger says.
Rise of alternatives
Such fissures within Wikipedia have already led to the rise of Grokipedia, an AI-generated online encyclopedia launched by xAI as a rival, with AI-written, fact-checked content and rapid updates.
Unlike Wikipedia’s volunteer-edited, transparent model, Grokipedia restricts direct user edits and currently hosts fewer articles. Critics warn that its sourcing and accuracy remain unclear, and reliance on AI may reduce verifiable citations.
Effects of altered data
Altered data on Wikipedia can mislead readers, distort history, damage reputations, and shape public opinion based on inaccuracies.
It undermines trust in open knowledge, widens information gaps for users with limited alternatives, and can influence education, journalism, and civic decisions.
In vulnerable communities, misinformation may reinforce stereotypes, policy mistakes, and digital inequality. This erodes accountability and democratic participation over time. – IOW Data.
