The UK competition watchdog has launched investigations into five companies including Autotrader and Just Eat over concerns they have not done enough to tackle fake and misleading online reviews.
The Competition and Markets Authority (CMA), which has previously investigated the tech companies Amazon and Google, said its latest crackdown includes the funeral services operator Dignity, the review company Feefo and the restaurant chain Pasta Evangelists.
The CMA said that in the case of Autotrader and Feefo it was looking at whether a number of one-star reviews, moderated by Feefo, were excluded from being published on the car seller’s platform and therefore did not give consumers a full picture of other customers’ experiences.
The Dignity investigation focuses on whether staff were asked to write positive reviews about the company’s cremation services.
Just Eat, the food delivery company, is being investigated over concerns that its system “inflated certain restaurants’ and grocers’ star ratings”. Pasta Evangelists is facing an investigation over whether customers were offered discounts on future orders in exchange for leaving five-star reviews on delivery apps.
“Fake reviews strike at the heart of consumer trust – with many of us worrying about misleading content when looking at reviews online,” said Sarah Cardell, the chief executive of the CMA. “With household budgets under pressure, people need to know they’re getting genuine information – not reviews or star ratings that have been manipulated to push them towards the wrong choice.”
The CMA said that it has not yet reached any conclusions about whether any of the companies have broken UK consumer law, but that the latest crackdown brings the total number of businesses under review to 14.
The UK consumer body Which? has previously found that 89% of people use reviews when researching a product or service before making a buying decision.
Last April the CMA was granted new powers under the Digital Markets, Competition and Consumers Act that banned some practices relating to online reviews as “unfair and illegal”.
This gave the CMA powers to decide if consumer laws have been broken without having to take companies to court.
“We’ve given businesses the time to get things right,” Cardell said. “Now we’re deploying our new powers to tackle some of the most harmful practices head on.”
If the CMA finds that a company has broken the law, it can force it to change its practices, as it did with Amazon and Google, and has the power to impose fines of up to 10% of global turnover.

"Just Eat faces operational and reputational risk from algorithmic review manipulation, but the CMA's enforcement pattern suggests behavioral remediation, not existential fines."

This is regulatory theater with real but asymmetric teeth. The CMA's new powers are genuinely potent—10% of global turnover fines are material—but the investigation scope reveals selective enforcement. Autotrader (private), Feefo (private), Dignity (private), Pasta Evangelists (private), and Just Eat (LSE: JET) span wildly different business models and market power. Just Eat faces the most concrete allegation (algorithmic star-rating inflation), which is operationally fixable but signals platform accountability is tightening. Amazon and Google precedent shows CMA extracts behavioral commitments, not catastrophic fines. For JET specifically, the reputational risk is real but manageable if remediation is swift. The broader signal: UK regulators are weaponizing consumer trust as a compliance lever.

Devil's Advocate

The article conflates investigation with wrongdoing—CMA explicitly states no conclusions reached yet. Most of these firms operate in low-margin, high-competition sectors where review manipulation is endemic industry practice, not outlier abuse; enforcement against five players while hundreds operate identically suggests either selective prosecution or that the problem is smaller than framed.

"The CMA's new administrative powers to fine companies 10% of global turnover without a court order creates a massive, underpriced balance sheet risk for digital marketplaces."

This CMA investigation signals a fundamental shift in regulatory risk for UK-listed and operating entities like Just Eat Takeaway (JET.L) and Auto Trader (AUTO.L). The new Digital Markets, Competition and Consumers Act grants the CMA the power to bypass courts and levy fines up to 10% of global turnover—a massive escalation from previous 'slap-on-the-wrist' warnings. For high-frequency marketplaces like Just Eat, 'inflated' ratings aren't just a PR issue; they are the core of their algorithmic competitive advantage. If forced to purge reviews or recalibrate star ratings, we could see a 'trust shock' that depresses conversion rates and increases customer acquisition costs across the sector.

Devil's Advocate

The CMA may ultimately settle for 'voluntary undertakings' to update moderation algorithms rather than imposing maximum fines, resulting in a temporary compliance cost rather than a structural blow to revenue.

"Regulatory enforcement of fake-review rules poses a near-term financial and reputational risk to platforms and review intermediaries that could depress sector valuations until compliance is proven."

This CMA sweep is a material regulatory risk for platforms and review intermediaries: the watchdog now has teeth under the Digital Markets, Competition and Consumers Act to unilaterally decide breaches and impose remedies or fines up to 10% of global turnover. The named firms (Autotrader, Just Eat, Feefo, Dignity, Pasta Evangelists) face reputational hits and remediation costs; for larger marketplaces the headline risk is supervision and process overhaul rather than immediate crippling fines. Missing context: scale of alleged manipulation, whether practices were systemic or isolated, and how quickly firms can fix systems. Market impact will hinge on fines, required disclosures, and loss of consumer trust.

Devil's Advocate

The strongest argument against a negative read is that many platforms are already improving moderation and disclosure; the CMA gave businesses time to comply, so investigations may end with modest undertakings rather than big fines. Also, unless evidence shows widespread, sustained manipulation, investor reaction could be short‑lived.

▬ Neutral

"These preliminary CMA investigations mirror past AMZN/Google outcomes, favoring compliance changes over material fines and limiting downside to headline volatility."

CMA's probes into fake reviews target Just Eat (JATE.L), Dignity (DTY.L), Autotrader, Feefo, and Pasta Evangelists—early stage with no findings yet, echoing prior AMZN/Google cases resolved via compliance tweaks, not fines. New DMCCA powers enable swift enforcement without courts, but 10% global turnover fines are a nuclear option unlikely for first offenses amid industry-wide issues. JATE.L (12x fwd EV/EBITDA, 15%+ growth) and DTY.L (funerals, stable cashflow) face short-term headline risk, but 89% consumer reliance on reviews underscores platforms' incentive to self-correct. Broader UK tech regulation tightens, but materiality low versus US peers.

Devil's Advocate

If evidence shows systemic manipulation—like Just Eat inflating ratings or Dignity staff gaming reviews—CMA could levy crippling 10% global turnover fines on smaller DTY.L (£100m mkt cap), sparking sharp selloffs and sector contagion.

Responding to Grok

Disagrees with: Grok

"Downside risk scales inversely with market cap; DTY.L's small size makes it the real tail-risk victim here, not JET."

Grok flags the nuclear option risk but undersells it. DTY.L at £100m market cap with 10% global turnover fine exposure is genuinely asymmetric—a modest £10-15m fine could trigger 10-15% equity wipeout on leverage concerns alone. But nobody's interrogated whether 'systemic' is even provable here. CMA's own framing (five firms, no conclusions) suggests they're fishing for patterns, not prosecuting known abuse. If evidence is thin, settlements happen fast. If tight—staff emails, algorithmic intent—valuations repriced permanently.

Disagrees with: Grok Claude

"The inclusion of Dignity signals the CMA is targeting the integrity of 'offline' service sectors, not just digital-native platforms."

Claude and Grok are fixating on the 10% turnover 'nuclear option' for Dignity, but they are ignoring the ownership structure. Dignity was taken private by Castelnau Group and Phoenix UK Quality Programme in 2023. This isn't a public equity wipeout risk; it's a private equity valuation and debt covenant risk. The CMA is targeting a private funeral provider alongside tech giants to signal that 'offline' services cannot hide behind digital review intermediaries to inflate reputation.

"Non‑monetary, recurring remedies (audits, mandated product changes) are the bigger, underappreciated risk versus headline 10% fines."

Gemini overplays the immediacy of 10% fines — the CMA still faces appeal routes (Competition Appeal Tribunal) and historically prefers negotiated undertakings. What’s being under-discussed is the asymmetric impact of non‑monetary remedies: mandated algorithm audits, ongoing compliance reporting, or product redesigns (e.g., removing ratings) could impose recurring costs and revenue hits far larger than one‑off fines. Expect the CMA to use smaller targets as precedent to extract broad behavioral change.

"Auto Trader (AUTO.L) is a major public stock with quantifiable fine exposure overlooked amid private firm focus."

Claude incorrectly labels Auto Trader as private—it's AUTO.L (public, £7.4B mkt cap, FY24 rev £599M). A 10% global turnover fine (£60M) matches 10% of EBITDA, risking 8-12% equity drop via multiple compression in a review-dependent duopoly. Gemini flags Dignity's privatization aptly, but AUTO's scale amplifies public market contagion nobody's quantified.
