Singapore Platforms Tighten Rules on Duplicate Images This Week as AI-Generated Content Floods Listings

Singapore's major digital listing platforms moved this week to enforce stricter duplicate image policies, catching thousands of property agents, small retailers and second-hand sellers off guard. The trigger: a surge in AI-generated and copy-pasted product images that regulators and platform operators say is distorting search results, misleading buyers and inflating the apparent size of inventories that simply do not exist.

The timing matters. Singapore's Infocomm Media Development Authority has been pressing digital platforms operating here to clean up user-generated content standards as part of its broader Digital Trust framework, which was updated in early 2026. Platforms that fail to demonstrate active moderation of misleading listings risk compliance reviews under the Online Safety Act, which came into full effect for commercial platforms last year.

What Changed This Week

Carousell, headquartered at 60 Anson Road in Tanjong Pagar, began auto-flagging listings where the uploaded image matched another active listing with more than 85 percent pixel similarity — a threshold its trust and safety team introduced on July 1. Sellers whose listings were pulled received in-app notifications directing them to the platform's updated content guidelines. Lazada Singapore, which operates its fulfilment hub in Jurong, issued a seller advisory on July 2 warning that duplicate main product images across multiple storefronts would result in listing suppression starting July 7.

The HDB Resale Portal, managed by the Housing and Development Board, has separately been rolling out image validation checks since May. Agents submitting flat listings on behalf of clients in estates from Tampines to Buona Vista have reported that the portal now rejects submissions where the uploaded floor plan or interior photograph matches a previously closed or delisted transaction. At least three PropNex agents contacted by The Daily Singapore this week described encountering the new rejection prompts for the first time, though none agreed to be named because they were not authorised to speak on behalf of their agencies.

The issue sits at the intersection of two pressures Singapore has been managing simultaneously: its ambition to be a regional AI hub, and the very real content-quality problems that AI tooling has introduced. Text-to-image generators have made it trivially easy to produce photorealistic room interiors or product shots. A four-room HDB flat in Sengkang marketed with a generated image of a Bishan showflat interior is not an abstract risk — it is a complaint pattern that the Consumers Association of Singapore logged across multiple quarters in 2025.

The Practical Impact on Sellers and Agents

For individual sellers, the immediate headache is re-photographing items or properties they had assumed were already adequately documented. Carousell's new flag does not automatically remove a listing — it places it in a 72-hour review queue, during which the item is invisible in search. For a seller moving a second-hand sofa in Clementi or a refurbished laptop in Ang Mo Kio, three days of search invisibility can mean the difference between a quick deal and a relist.

Real estate agencies are facing a more structural rethink. The Council for Estate Agencies, which licenses agents island-wide, had already required accurate visual representation of properties under its Code of Ethics. The HDB portal's technical enforcement now makes that obligation automatic rather than aspirational. Agencies that built workflows around recycling stock photography from previous listings — a common shortcut in high-volume rental markets like Jurong East and Woodlands — will need to update those pipelines before July 15, when HDB says the validation layer becomes mandatory rather than advisory.

Photographers who specialise in property and product work say enquiries have jumped noticeably since Monday. Studios around Tai Seng and Ubi Avenue 4, which cater to e-commerce sellers, reported booking queues extending into late July.

For sellers and agents navigating the new rules, the clearest path forward is original photography — ideally geotagged — and a single canonical image set used consistently across platforms. Carousell's updated guidelines, posted publicly on July 1, specify that listings appealing a duplicate flag must include a photograph with a visible timestamp or a Singapore landmark in frame as proof of originality. It is an unglamorous fix, but the platforms appear to have decided that the cost of enforcement is lower than the cost of continued trust erosion.
