Car detailing firm admits to posting fake AI-generated 5-star reviews on Sgcarmart in first such case
Quantum Globe, the owner and operator of Lambency Detailing, admitted to submitting the ChatGPT-written reviews using their customers' information without their knowledge and consent.
'This is the second fake review case that CCCS has uncovered, and the first case involving both a third-party platform and the use of AI to create these fake reviews," said CCCS chief executive Alvin Koh.
The consumer watchdog began investigating the case in January under Singapore's fair trading laws.
This came after a complaint from a Lambency Detailing customer who discovered unauthorised reviews posted under her name on Sgcarmart, an online platform for buying and selling cars. According to its website, Lambency Detailing provides a range of car detailing services from hand washing to restoration.
During the investigation, CCCS confirmed with seven other customers that fake reviews with their names, vehicle registration numbers and vehicle photographs had been posted without their consent.
Quantum Globe then admitted it was behind the reviews, and that it had used ChatGPT to generate them based on services it had provided to the customers.
The reviews were submitted via a QR code provided by Sgcarmart that allowed users to give feedback on businesses without needing to have an account with the platform, Facebook or Google.
"The posting of fake customer reviews by a business in relation to a consumer transaction is an unfair trade practice, as consumers might be misled into thinking that the product is more well-received than it actually is, and thus make misinformed purchase decisions," said CCCS.
ACTION TAKEN
According to CCCS, Quantum Globe has admitted to engaging in an unfair trade practice and has given an undertaking that it will stop posting fake reviews.
The company also agreed to set up a feedback channel for six months to allow the reporting of any fake reviews on Sgcarmart by customers.
It will notify customers whose details were used in the fake reviews that were posted between October 2024 and January, and invite them to report fake reviews via the feedback channel.
In addition, Quantum Globe agreed to publish notices that will last for six months on Sgcarmart and any other online platforms it uses to promote Lambency Detailing. The notices are to inform customers that it had posted fake reviews and to let them know of the feedback channel.
Any reviews on Sgcarmart that are verified to be fake are to be removed within eight working days, including the reviews flagged by CCCS during its investigation.
Quantum Globe director Matthew Lim Jun Ho also gave an undertaking to CCCS that he will not engage in any unfair trade practice or facilitate any business under his control to do so.
In response to the investigation, Sgcarmart owner and operator SGCM is considering additional verification methods, such as SMS or email confirmation, to enhance the integrity and authenticity of reviews on its platform, said CCCS.
In June last year, furniture retailer Loft Home Furnishing was issued a warning by the consumer watchdog for posting fake 5-star reviews. Investigations into that case were prompted following complaints by some customers over reviews which contained their initials and posted on the retailer's website without their knowledge.
"When businesses post fake reviews to boost their ratings and popularity, they poison the well of consumer trust. Such deceptive practices, also known as 'dark patterns', not only mislead consumers but also disadvantage honest competing businesses," said Mr Koh.
"We remain committed to take firm action against businesses engaging in such unfair practices."
Consumers who rely on online reviews before making purchases are advised to spend more time looking in-depth, rather than just scanning them.
"Instead of just focusing on the number of reviews and the average score, look deeper into the spread of review scores and common opinions that emerge. Read a selection of reviews with different scores and form your own view," said CCCS.
Other measures they can take to differentiate authentic reviews from fake ones include checking multiple websites to gauge the consistency and reliability of the reviews, as well as whether there are safeguards in place, such as verification of purchases and absence of incentivised reviews.
Overly positive reviews can be a red flag, as are generic reviews that lack details or use generic buzzwords such as "amazing" or "perfect".
Consumers should also be wary if there are many reviews posted under similar names, using similar language, or have repeated or similar spelling or grammatical errors, said CCCS.

Man jailed for driving into fellow private-hire driver after causing taxi stand collision
SINGAPORE: After causing a collision at a taxi stand because he forgot to engage his handbrake, a private-hire driver accelerated matters by suddenly driving off, hitting the other driver as a result. Aiden Ang Wee Hao, 33, was jailed for two weeks on Monday (Jul 7) and banned from driving for a year. The Singaporean pleaded guilty to one count of causing hurt by a rash act endangering personal safety. The court heard that Ang was working part-time as a private-hire driver in December 2023. At about 9.20pm on Dec 8, 2023, he dropped off four passengers at the taxi stand of The Centrepoint in Orchard Road. After the passengers had alighted, Ang stepped out of his seat to check on the car, but forgot to change his gear to "park" or engage his handbrake. The grey Mazda moved forward and collided with the back of a black Toyota Sienta, driven by Mr Yap Chee Hian, a 61-year-old full-time private-hire driver. Mr Yap was picking up passengers from the same taxi stand. After the collision, Mr Yap got out of his vehicle and both men discussed insurance claims and compensation for the accident. There were no threats, vulgarities or insults made, nor any shouting, the court heard. About three-and-a-half minutes into their conversation, Ang went back into his car and closed the door while Mr Yap continued talking to him. Mr Yap then made a call on his phone mid-conversation. Both men had not exchanged contacts. Mr Yap tried to talk to Ang while on the phone, but Ang started to reverse his car. Mr Yap responded by tapping on Ang's windscreen to get his attention. Ang paused briefly to talk to Mr Yap, but suddenly accelerated and turned his vehicle left to the adjacent lane to exit the taxi stand. Mr Yap dashed forward along Ang's car and slapped his bonnet once, but Ang continued moving for several metres until Mr Yap ran directly in front of his car. Even after Mr Yap had positioned himself in front of Ang's car, Ang continued to inch his car forward, such that Mr Yap ended up with his torso leaning over the bonnet. Mr Yap kept trying to communicate with Ang, slapping the bonnet again to get the car to stop. Ang briefly stopped his car and Mr Yap moved several steps backwards while using his phone. He then immediately drove forward, stopping only when his car made contact with Mr Yap's knee. Ang then reversed before lurching forward and braking just before contact with Mr Yap. Mr Yap flinched in anticipation, and Ang reversed his vehicle again until it was behind Mr Yap's car. This time, he turned right to rejoin the main road. Mr Yap tried to move in front of Ang's car again to stop him from leaving, but Ang continued accelerating even after driving into Mr Yap's right leg. The collision caused Mr Yap's leg to buckle, with Mr Yap's upper body sprawled over Ang's bonnet. Ang continued accelerating away and Mr Yap fell to the ground just beside Ang's front wheel. Ang then cut across the flow of traffic to make a U-turn before speeding off from the scene. The victim was taken to hospital with slight pain in his hip and buttock areas, with likely bruises. He was discharged that same day and given four days of outpatient sick leave. HIGH DEGREE OF RASHNESS: PROSECUTOR The prosecutor sought the sentence that was eventually meted out, noting that Ang had no previous convictions and had pleaded guilty as early as he could. He noted the "high degree of rashness" Ang demonstrated, whose actions "bordered on being intentional". "The accused showed a sustained pattern of driving aggressively by inching his car forward multiple times even when the victim was positioned directly in front of him," said Deputy Public Prosecutor Timothy Ong. "During the last collision with the victim, the accused accelerated into the victim despite the victim's position in front of the accused's car being clearly visible to the accused in the driver's seat," he added. Mr Ong said Ang's rash driving and attempt to leave the scene must be seen "against the backdrop of his refusal to provide his particulars to the victim", after his "careless failure to secure the handbrake had caused a collision between two vehicles".

S$1.5b nickel fraud trial: Accused swindler Ng Yu Zhi declines to testify, defence closes case
SINGAPORE: Ng Yu Zhi, the businessman at the heart of an alleged nickel investment fraud involving almost S$1.5 billion (US$1.17 billion), declined to testify in his case on Monday (Jul 7). Ng, 38, who ran Envy Global Trading and Envy Asset Management, chose to remain silent and accepted that the judge could draw an adverse inference from his choice to do so. He made this decision after speaking with his lawyers for under an hour on Monday morning. Defence lawyers Hassan Esa Almenoar and Nichol Yeo had no other witnesses to call, and the defence closed its case. Both the prosecution and defence are to file their closing submissions on whether or not Ng should be convicted, with a verdict to be given later. Lead prosecutor Gordon Oh said he had discussed the matter with the defence and it would be "preferable" to have the verdict on Aug 22. Judicial Commissioner Christopher Goh took note of that but said he would give the verdict date at a later time in case of any further developments or queries he may have. Ng went on trial in November facing 42 charges, including forgery, handling benefits from criminal conduct, cheating, fraudulent trading and criminal breach of trust. He has another 66 outstanding charges, but these were stood down or set aside for the time being while this trial goes on. THE CASE The prosecution's case is that Ng attracted hundreds of investors over five years from February 2016 with his companies' purported physical nickel trading. They said Ng was the scheme was Ng's "brainchild", but the nickel trading was "fiction" that he conveyed to investors either personally or through his sales representatives. Alleged victims of the scheme include lawyers and a venture capitalist, who testified about how he was "impressed" by Ng. Ng then lived lavishly on the proceeds of the fraudulent scheme, alleged the prosecutors, withdrawing at least S$201.2 million from Envy Global Trading to his personal bank accounts. He spent it on expensive artworks, property, cars and jewellery, charged the prosecutors. Over six years, Ng's companies received a total of S$1.46 billion in investments from 947 investors. Of this, about S$482 million was channelled to Ng's personal bank accounts. Ng was initially on bail running into the millions, but he was remanded after breaking bail conditions by allegedly committing fresh offences. His latest request for bail was rejected by the court last week.

Thai headline inflation negative for 3rd straight month in June
BANGKOK :Thailand's annual inflation rate was negative for a third straight month in June, driven by lower energy and food prices, but the commerce ministry said on Monday there was no sign of deflation yet. The consumer price index dropped 0.25 per cent in June from a year earlier, bigger than the 0.1 per cent decline forecast in a Reuters poll, and following a 0.57 per cent drop in the previous month. It was the fourth month in a row that the inflation rate has been below the central bank's target range of 1.0 per cent to 3.0 per cent. Headline inflation in the third quarter is expected to remain negative before turning positive in the final quarter of the year, Poonpong Naiyanapakorn, head of the commerce ministry's Trade Policy and Strategy Office, told a press conference. There were no signs of deflation because the price drop was driven by lower energy prices, he said. The core CPI, which excludes volatile fresh food and energy prices, rose 1.06 per cent in June from a year earlier, compared with a forecast increase of 1.10 per cent. In the first six months, annual headline inflation averaged 0.37 per cent, with core inflation at 0.97 per cent, the ministry said. The ministry maintained its headline inflation forecast for 2025 at 0.0 per cent to 1.0 per cent. Last month, the central bank left its key interest rate unchanged at 1.75 per cent, seeking to save some policy ammunition if needed to support the economy amid trade uncertainty and renewed domestic political turbulence. The next rate meeting is on August 13.
