Chris Emmins, co-founder of KwikChex, an online reputation management firm, represented approximately 2,000 UK hoteliers who had been damaged by fake reviews on TripAdvisor. In 2011, KwikChex filed a complaint with the UK Advertising Standards Authority (ASA) challenging TripAdvisor's marketing claims: "reviews you can trust," "read reviews from real travellers," and "more than 50 million honest travel reviews."
The evidence
KwikChex provided the ASA with "unequivocal proof of large scale review fraud," demonstrating how easily fake reviews — including unsubstantiated allegations of food poisoning and claims of theft — could be posted on TripAdvisor without any verification.
The ruling
On February 1, 2012, the ASA upheld the complaint. The ruling stated:
"We told TripAdvisor not to claim or imply that all the reviews that appeared on the website were from real travellers, or were honest, real or trusted."
— UK Advertising Standards Authority, February 2012
TripAdvisor had already begun replacing "reviews you trust" with the more generic "Reviews from our Community."
"We did this because we think that the greatest impact is very much on small businesses."
— Chris Emmins, KwikChex
What this case reveals
A national advertising regulator officially ruled that TripAdvisor's core claim — that its reviews could be trusted — was misleading. That was in 2012. Over a decade later, the fundamental problem remains: no major review platform can guarantee that the reviews it hosts are from real customers, yet billions of booking decisions are made based on those reviews every year.
