Just Eat and Autotrader among firms investigated in fake reviews probe
Nearly 50% of reviews visible online may be fake, undermining the foundation of consumer trust and impacting billions of pounds spent annually. The British regulator, the Competition and Markets Authority (CMA), has launched an official investigation into five market giants, including the Just Eat platform and the automotive service Autotrader. The probe aims to determine whether these companies violated consumer law by manipulating opinions, hiding negative comments, or artificially inflating ratings. The allegations vary: Just Eat is being scrutinized for algorithms that pump restaurant ratings, while Pasta Evangelists may have offered discounts in exchange for undisclosed five-star reviews on delivery apps. Meanwhile, Dignity is suspected of encouraging employees to write flattering reviews of their own services. For global users of creative technologies and e-commerce, this is a signal that the era of impunity for "review factories" is coming to an end. Regulators have gained new powers allowing them to impose heavy financial penalties without court proceedings, forcing brands toward greater transparency in content moderation. The practical significance for everyone is clear: maintain a distance from perfect ratings, verify reviews across multiple sources, and watch for overly "polished" language, which often betrays the interference of AI or paid copywriters. The fight for online authenticity is entering a phase of uncompromising enforcement of ethical standards.
In the era of a digital economy based on trust, rating systems have become the currency that determines the success or failure of almost every business. However, this currency is increasingly being forged. The British market regulator, the Competition and Markets Authority (CMA), has just announced the launch of a large-scale investigation targeting five major market entities. Established companies such as food delivery giant Just Eat and the popular automotive site Autotrader are in the crosshairs. The allegations are serious: from manipulating average ratings and hiding negative opinions to paying for reviews with discounts.
The scale of the problem is enormous. According to data from research firm TruthEngine, up to 50% of reviews on the internet may be fake. In a world where online reviews influence spending worth billions of pounds annually, every manipulation directly hits consumers' wallets. Sarah Cardell, CEO of the CMA, emphasizes that in the face of growing pressure on household budgets, users must have access to reliable information, not a "curated image" designed to lure them into making the wrong choice.
Manipulation mechanisms under the regulator's microscope
The CMA investigation does not focus on a single model of abuse but exposes various techniques used by companies to improve their image. Each of the investigated entities must respond to different allegations, showing how creative marketing departments can be in bypassing market ethics. The regulator is analyzing the processes of acquiring, moderating, and presenting reviews to check whether consumer law has been violated.
A new era of penalties and the fight against tech giants
This investigation is one of the first such clear displays of the CMA's strength after gaining new powers in April last year. Currently, the regulator can impose high financial penalties on companies violating consumer law without the need to take the case to court. This is a significant change, as the institution was previously criticized for being too lenient toward tech giants. Examples include Amazon and Google, which in the past avoided formal decisions on law violations by only agreeing to voluntary commitments to improve their systems.
It is worth noting that regulatory pressure is yielding results. In January 2025, both Google and Amazon agreed to introduce significant changes to their review verification processes. However, the problem does not only concern large corporations. Fake reviews have also become a criminal tool – in 2024, cases were recorded of criminal groups blackmailing small, independent restaurants, threatening to flood their profiles with negative ratings if a protection fee was not paid. This shows that the rating system, instead of protecting the consumer, has become a battlefield where reliability is a scarce commodity.
How to recognize manipulation in a thicket of stars?
In the face of the trust crisis in 5-star systems, the CMA has issued a set of recommendations for users. The key is to move away from relying solely on the average rating in favor of a thorough reading of the review content. The regulator warns against reviews generated by artificial intelligence – if the text seems "too smooth" or unnaturally perfectly phrased, there is a high probability it was not written by a human. Instinct proves to be a better advisor than an algorithm here.
Paradoxically, three- or four-star ratings are often the most reliable. As the CMA notes, real customers are rarely uncritical – they might deduct a point for a minor delivery delay or a damaged package, which paradoxically validates the rest of their positive opinion. The strategy of checking multiple independent sources instead of relying on a single platform is now becoming the only effective way to avoid the trap of marketing manipulation.
"Investigations are a welcome first step, but enforcement will be key. The regulator must be ready to play hard and impose stiff penalties if companies don't follow the rules," says Sue Davies from the consumer organization Which?.
The current CMA offensive against Just Eat, Autotrader, and the other companies sets a new standard in digital market oversight. The era where platforms could "clean" comment sections of inconvenient facts or buy user favor with discounts with impunity is coming to an end. In the coming months, we will see if the regulator's new powers to impose direct financial penalties will be enough to restore reviews to their original function – being a reliable guide for the consumer, not a tool for sales engineering.
