The AI arms race in online reviews: How businesses are battling fake content

Written by on January 13, 2026

What was once a simple signal for trust has become a place where potential customers feel like they have to keep a watchful eye. Reviews, including star ratings and written testimonials, have been overtaken by generative AI, automation, and increasingly commissioned reviews. As large language models (LLMs) lower the cost of producing content at scale, online reputation has become a greater risk for customers. Today, online reputation management (ORM) means having AI safety under control, platform governance, and creating a trustworthy infrastructure.

The rise of fake reviews

Fake reviews are no longer only written by paid actors. They have become entirely industrialized. Some estimates suggest that billions of dollars in global consumer spending are influenced by fraudulent or manipulated reviews. Some analyses even suggest the total economic impact could be in the hundreds of billions. 

The problem isn’t just negative attacks on businesses. A significant share of disingenuous reviews are five-star ratings designed to inflate a product’s visibility, manipulate ranking algorithms, and crowd out legitimate competitors. 

Generative AI has only made this trend worse. Newer LLMs can generate context-aware, sentimental-sounding reviews that go as far as referencing the product’s specific features, details, or nuances found from other online reviews. When bot networks are given access to old accounts, these systems can produce entire review campaigns that evade the traditional anomaly detection filters. For platforms, the ratio of honest reviews to fake ones is deteriorating faster than the filtering systems can adapt.

Why the review economy is fundamentally broken

The assumption that more reviews mean more trust has proven to be flawed. In practice, artificially positive reviews distort consumers’ perception just as much as low-rating attacks. Both undermine fair competition within the market and the brand’s long-term credibility. 

Small and mid-sized businesses are disproportionately affected. Many operate in small or niche markets, where having even a handful of reviews can significantly increase the number of customers they attract. This has created the perfect grounds for fraudulent schemes: bad actors threaten to post waves of fake negative reviews unless businesses pay them to avoid reputational damage. Since platforms often have slow, manual dispute processes, the leverage tends to favor the attackers. 

Once that trust is broken, the market stops rewarding genuine quality and instead rewards whoever best understands how to game the system. At that point, reputation isn’t about customer experience; it’s about being resilient in a different kind of economy.

Platform weaknesses: The rise of ORM as a technical discipline

Major review platforms use a mix of automated categorization, heuristics, and human moderation. While this is usually effective against low-effort spam bots, these systems struggle with harsher cases, such as reviews that are factually plausible, sound human, and are statistically “normal” when reviewed in isolation. 

The lack of updated review technology has led to a more technical form of online reputation management. Modern ORM focuses on reverse-engineering a platform’s mechanics. Practitioners analyze reviews’ metadata, user account histories, posting frequency, linguistic abnormalities, and alignment with platform policies to determine whether content violates the rules. 

Reputation management companies function as a specialized compliance and diagnostics team. They enforce platform-specific policies, identify violations, and go through the formal dispute processes with concrete evidence. This is a notable difference from the former practices that would often unknowingly allow artificial reviews. 

A case study for the new ORM model

Erase.com is an example of this newer generation of ORM services. It operates within existing platform and search engine frameworks. It doesn’t just remove bad reviews; it also diagnoses whether content meets policy standards for authenticity, relevance, and user experience.

The company conducts large-scale review analyses, platform-specific dispute workflows, and search result remediation using documented guidelines. The emphasis is on data-backed arguments, helping defend companies from malicious attacks quickly. While this is not the only company using this new ORM model, it demonstrates how reputation management has become a necessary layer for many companies when addressing systemic weaknesses in their reviews. 

Working towards an industry-wide response

The current trajectory for trustworthy reviews is bleak if platforms continue to operate as they are. Several new solutions are already being explored. Real-time AI-backed verification tools could flag suspicious content before it impacts rankings, while a blockchain-based system may offer stronger guarantees of authenticity. 

At the same time, consumer awareness still matters. As AI-generated content becomes more abundant, signs of trust may come from smaller details, such as a reviewer’s history, their language, and verification on the platform. Ultimately, the fight against fake reviews can’t be won alone. As automated content becomes increasingly sophisticated, online reputation management will become a crucial discipline for maintaining trust.
