Ofcom proposes mandatory ad transparency data for third-party fraud auditing
Ofcom experts are recommending that ad platforms provide trusted third parties with access to representative random samples of active ads to combat fraud and verify integrity. The report also suggests that platforms should proactively flag fraudulent ad activity to users rather than treating it as a solely user-reported issue.
Key Takeaways
- Platforms would be required to share large, representative random samples of all active ads and total ad counts with verified third-party sources.
- Proposed rules would mandate that platforms proactively notify users who interact with ads later confirmed to be fraudulent or part of scam campaigns.
- Experts highlighted a misalignment in existing incentives, noting that platforms currently profit from fraud by retaining revenue or issuing only ad credits for scammed impressions.
- The recommendations seek to address 'pig-butchering' and financial scams often hosted on major search and social media interfaces without repayment to victims.
Why It Matters
This move shifts the burden of ad integrity from the buyer to the platform, potentially ending the 'risk-free' revenue models for providers that host fraudulent placements. For the streaming and digital ecosystem, this signals a transition toward standardized, audited transparency that could disrupt current opaque 'black box' ad delivery systems. If adopted, this framework forces tech giants to prioritize scam removal over short-term CPM gains by turning fraud into a liability rather than a profit center. Watch for the mid-2027 enforcement deadline for final UK codes, which may set a global precedent for ad-supported VOD and CTV platforms.
Additional Context
The draft Fraudulent Advertising Code, released by Ofcom in July 2026, marks a critical implementation phase of the UK’s Online Safety Act (OSA). According to Ofcom’s own reporting from July 2026, over 50% of UK adults have encountered fraudulent ads online, with victims losing an estimated £200 million annually. The proposed code includes approximately 40 practical measures, such as mandatory verification for advertisers promoting financial services and requirements for platforms to prevent known scammers from re-registering accounts. Failure to comply with these rules once finalized could result in fines of up to 10% of a platform’s global annual revenue. This regulatory push aligns with a broader international trend toward ad repository transparency. Per the European Commission in May 2026, Very Large Online Platforms (VLOPs) under the Digital Services Act (DSA) are already being forced to store ad data in publicly accessible repositories. In July 2026, the Commission accepted a specific action plan from X (formerly Twitter) to improve its ad repository API access for researchers, addressing previous deficiencies in identifying the entities paying for specific campaigns. Industry groups are already signaling the operational challenges of these mandates. While ISBA, the UK’s body for advertisers, welcomed the crackdown in July 2026, it noted that "reputational damage" from imposter ads remains a top-tier concern for legitimate brands. Organizations like the IAB UK have highlighted that while transparency is necessary, the responsibility for pursuing actual criminals must remain with government law enforcement, not just the technical intermediaries. As these codes move toward Parliamentary approval, the digital advertising supply chain faces a 12-month window to integrate proactive detection technologies ahead of full enforcement in 2027.
