'My whole portfolio was wiped out': Hong Kong sellers speak out on the duplicate image crisis hitting online platforms

Dozens of Hong Kong-based sellers and independent photographers say automated duplicate-image detection systems used by major e-commerce and stock photography platforms have wrongly pulled their product listings and creative work — sometimes permanently — leaving them with no revenue and no clear path to reinstatement. The problem has been building for months, but complaints have reached a critical mass in recent weeks, with affected users in Mong Kok, Kwun Tong and Sham Shui Po reporting near-simultaneous account suspensions in June 2026.

The timing matters. Hong Kong's retail sector is still clawing back ground after years of subdued consumer spending, and small online vendors — many of them operating out of industrial units in the Kwun Tong industrial belt or from shopfront studios along Fa Yuen Street — have come to rely on platforms such as Carousell, Taobao cross-border storefronts, and international stock libraries as primary income sources. For photographers licensing images through Getty and Shutterstock, a wrongful duplicate flag does not just kill one listing. It can trigger a cascade of takedowns across an entire catalogue.

What the platforms are doing — and what they are not

The mechanics of the problem are not mysterious. Platforms use perceptual hashing — a technique that generates a fingerprint for each image — to detect copies. When a seller re-uploads a product shot after editing the background or adjusting the colour grade, the system can still read it as a duplicate of a competitor's image, especially if the underlying product is common. A Mong Kok wholesaler selling generic phone accessories described losing 340 active listings in a single automated sweep in late May. A Sham Shui Po fabric trader said her account, built over four years, was suspended with 48 hours' notice after a bulk re-upload following a store redesign.

Hong Kong's Consumer Council received a rise in platform-related complaints during the first quarter of 2026, and the Hong Kong Photographers Association — based in Wan Chai — has been fielding calls from freelancers whose stock library income has dropped sharply after images were delisted. The association has written to at least two major platforms requesting clarification on appeal timelines, according to a notice circulated to its membership in June 2026. The platforms have not publicly responded.

For context on scale: Carousell reported more than 1.5 million monthly active users in Hong Kong as of its most recent available figures, and the stock photography market in Asia-Pacific was valued at over US$1.2 billion in 2025, according to industry research firm Statista. Even a small error rate in image-matching algorithms translates into thousands of legitimate listings pulled without cause.

Navigating the appeals maze

The frustration is not only the initial removal. Multiple vendors in Kwun Tong described waiting more than three weeks for a response to a formal appeal, only to receive a templated rejection that did not address the specifics of their case. A commercial photographer who licenses architectural work through two international platforms said her income from those sources fell by roughly 60 percent in June after 80 images were flagged — images she had shot herself from the rooftop of a building on Hoi Yuen Road.

The Hong Kong Trade Development Council's SME Centre in Wan Chai has begun including platform dispute guidance in its one-on-one advisory sessions for online sellers, according to its published June programme schedule. Advisers there are directing affected traders toward formal written complaints referencing the specific hash match data — information platforms are required to provide under their own terms of service, though few sellers know to ask for it.

For sellers dealing with wrongful takedowns now, the most actionable step is to request the exact perceptual hash identifier used to flag the image and file the appeal with that reference number attached. Resubmitting a slightly altered image without first resolving the original flag will typically trigger a second suspension. Legal clinics at the Law Society of Hong Kong on Wyndham Street in Central offer duty lawyer consultations that cover e-commerce intellectual property disputes, with sessions available on the first Tuesday of each month at no cost to qualifying small businesses.
