Fake Review Scams

Fake review scams use manufactured or manipulated customer feedback to make products, sellers, or services appear more trustworthy, popular, or high-quality than they are. The fake reviews may take the form of purchased five-star ratings submitted by paid reviewers who did not genuinely buy the product, incentivised reviews where customers were offered free products or payment in exchange for positive feedback, or review hijacking where a seller replaces a legitimate product listing's reviews with their own inferior product.

Reviews are a primary decision-making tool for online shoppers. Research consistently shows that the volume and average rating of reviews significantly influences purchase decisions, and that consumers often assume they can identify fake reviews by reading them carefully. In practice, distinguishing fabricated reviews from genuine ones without specialist tools is difficult, particularly when the fake reviews are professionally written and avoid obvious red flags.

The harm is typically indirect. The victim does not lose money to the review operation itself — they lose it when they buy the product the fake reviews endorsed: a low-quality item that does not perform as described, a counterfeit, or in more serious cases, a product that turns out not to exist at all. Fake reviews are the mechanism that makes other scams more convincing.

In some variants, the review manipulation is more aggressive: sellers pay for negative reviews to be posted on competitors' listings, or use review hijacking to inherit an existing product's positive review history for a completely different item.

Several distinct methods are used to manufacture or manipulate reviews. In the purchase model, sellers pay individuals — often through third-party services — to buy the product, leave a five-star review, and then receive a full cash refund, meaning the reviewer has not actually used the product at any cost to themselves.

In the incentivised review model, sellers offer free products, discount codes, or cashback in exchange for positive reviews. These may not always be disclosed as incentivised, which is against the policies of most major platforms and in some jurisdictions is a legal disclosure requirement.

Review hijacking exploits a loophole that has appeared on major marketplaces where a seller can modify or replace a product on an existing listing. The new product inherits all the reviews from the previous product, even though those reviews describe something entirely different. A shopper reading five-star reviews about a high-quality item may be purchasing a different, inferior product that replaced it.

A fourth method is bulk-reporting competitors' genuine reviews as fake to have them removed, while simultaneously adding purchased positive reviews to the attacker's own listings. The combined effect distorts the comparative rating landscape.

Reviews function as social proof — the most powerful form of persuasion in consumer decision-making. A product with thousands of five-star reviews and specific, detailed testimonials activates trust in a way that advertising does not. Shoppers use reviews as a shortcut to verify that other people like them found the product worthwhile.

The sophistication of review fabrication has increased with the availability of services that generate plausible, varied, human-sounding reviews at scale. Reading a fake review critically requires specific knowledge of what linguistic or structural patterns indicate fabrication, knowledge that most shoppers do not have.

A shopper evaluates two similar products on a marketplace. One has a handful of mixed reviews; the other has several hundred five-star reviews with detailed positive descriptions. They choose the better-reviewed option and order it. When the item arrives, it does not match the quality described in the reviews. On closer inspection, the listing was recently created and the reviews describe a different product that was on the listing previously. The shopper opens a dispute with the marketplace citing the product as not as described.

When evaluating reviews, look for patterns that suggest manipulation. Unusually large clusters of reviews submitted within a short period — particularly at a product's launch — are a warning sign. Reviews that use similar language, focus on the same specific details, or are all five stars with no lower ratings suggest an unnatural distribution.

Use independent review analysis tools where available. Some browser extensions and third-party services analyse review authenticity and flag suspicious patterns. These are not infallible but can surface obvious manipulation.

Search for the product name independently and look for reviews or discussion outside the platform where you are shopping. Independent forum posts, consumer advice communities, and comparison sites provide context that is harder to manipulate.

For listings on major marketplaces, check the product's listing history if the platform makes this available. A very recent listing date with thousands of reviews is a strong indicator of review importation or hijacking.
