DoubleVerify launches automated filters to block illicit CSAM and P2P content

The immediate implication is a shift toward default automated blocking for the most high-risk content segments, moving beyond traditional manual exclusion lists. As the industry faces increased scrutiny over ad-supported monetization of illegal content, this move attempts to establish a safety baseline that covers both web domains and mobile applications. In the broader ecosystem, this puts pressure on competitors and programmatic exchanges to adopt similar open-source or shared risk databases. Watch for whether platforms like Google and Amazon officially integrate these specific DV categories, as their involvement is critical for industry-wide scale.

The launch of these automated categories follows a period of intense pressure on the ad verification sector. Per Digiday in February 2025, U.S. Senators Marsha Blackburn and Richard Blumenthal sent formal inquiries to the CEOs of DoubleVerify, Integral Ad Science (IAS), and the Media Rating Council (MRC) after a report from Adalytics alleged that major brand advertisements were appearing on websites hosting child sexual abuse material (CSAM). The senators specifically questioned the industry’s reliance on automated tools and the lack of granular page-level data shared with advertisers.

Simultaneously, the Media Rating Council has begun enforcing stricter standards for what can be marketed as "brand safety." Per PPC Land in October 2025, the MRC issued a policy requiring that vendors must possess content-level analysis capabilities—including image, video, and audio cues—rather than just domain-level or keyword checks to maintain accreditation. This shift is intended to close the "blind spots" in programmatic buying where illegal or unsuitable content slips through traditional text-based filters.

To further bolster its capabilities, DoubleVerify expanded its partnerships to include European authorities. Per a company announcement in April 2025, DV partnered with the Internet Watch Foundation (IWF) to incorporate its URL list of known CSAM webpages into the "Highly Illicit" category. This proactive stance comes as major tech companies navigate shifting regulatory landscapes; for instance, the MRC recently revoked Meta's content-level brand safety accreditation after the company withdrew from the annual audit program in September 2025, according to MediaPost.
