Are We Arguing With Bots? How Synthetic Engagement Hijacks the Digital Public Square

Online discourse today is increasingly shaped not by human voices, but by automated entities designed to mimic them. Bots and troll farms, often operating under the radar, have become central players on platforms like X (formerly Twitter), Facebook, and Reddit. These accounts are programmed to amplify narratives, distort perceptions, and simulate social consensus. In 2020 alone, Twitter estimated that nearly 5% of its users were bots, although independent research suggests the number could be significantly higher in certain politically charged conversations¹. Facebook has reported removing over 1.3 billion fake accounts in the first quarter of 2021, a testament to the scale of the issue².

These automated actors are not limited to spreading spam or low-grade propaganda. Sophisticated bots are now capable of engaging in nuanced conversations, retweeting specific hashtags at optimal times, and creating the illusion of widespread support or opposition. This synthetic engagement manipulates algorithms that prioritize popular or trending content, causing false narratives to rise to the top of public feeds. The design of these platforms, which reward engagement over accuracy, makes them especially vulnerable to this type of manipulation. Consequently, what users interpret as organic public sentiment is often a coordinated effort driven by a minority of automated or bad-faith actors.

Disinformation Cascades: How Falsehoods Spread Faster Than Facts

One of the most vexing characteristics of modern digital discourse is the speed with which misinformation proliferates. Research published in the journal Science found that false news stories on Twitter spread significantly farther and faster than the truth, particularly in areas related to politics and health³. This diffusion pattern is exacerbated by platform algorithms that prioritize content with high engagement, regardless of its veracity. In effect, the emotional appeal and novelty of misinformation often make it more shareable than well-sourced, factual information.

Public administrators and communication professionals must understand that these dynamics are not accidental. Disinformation campaigns are often the product of deliberate strategy, where bad actors test multiple messages and amplify those that generate the most traction. On Reddit, for example, coordinated brigading by troll accounts has been observed during election cycles, where users are directed to downvote or upvote specific content to manipulate visibility⁴. These tactics distort the apparent consensus in online spaces, making it harder for genuine users to discern reliable information. For governments and civic leaders, this poses a serious challenge to informed decision-making and public trust.

The Blurred Line Between Human and Machine

The rise of AI-generated personas adds another layer of complexity. These digital entities are designed to appear human in every respect: they post regularly, respond to comments, and even express opinions consistent with targeted demographic profiles. Tools that generate realistic profile pictures and language models capable of crafting contextually appropriate responses have made it nearly impossible for the average user to distinguish between a real person and a synthetic one⁵. This deception is not merely technical - it has social and political implications.

In public forums where policy issues are debated, such as Facebook community groups or Reddit threads focused on urban planning, synthetic accounts can sway sentiment by sheer volume. When enough AI-generated voices appear to support a position, it creates a false consensus that may influence actual public opinion or, worse, decision-making by officials monitoring these discussions. For communication officers and speechwriters in government, acknowledging the presence of these synthetic participants is essential when gauging
