WASHINGTON, D.C. – Today, U.S. Senators Marsha Blackburn (R-Tenn.) and Richard Blumenthal (D-Conn.) sent letters to several digital advertising platforms after a bombshell report revealed they placed advertisements on a website known to host and distribute Child Sexual Abuse Material (CSAM). 

This report was shared exclusively with the Senators before public release. Senators Blackburn and Blumenthal sent letters detailing the report to AdTech vendors Google and Amazon, ad verification firms DoubleVerify and Integral Ad Science, and industry standards bodies Media Rating Council and Trustworthy Accountability Group. Below are excerpts from their letter to Amazon.

Blackburn & Blumenthal Sound the Alarm on Amazon Tech Being Used to Monetize Websites that Host Child Sexual Abuse Material

“We write to express our profound concern that Amazon’s technology has been used to monetize websites that have been known to host child sexual abuse material (CSAM). Recent research indicates that Amazon has facilitated the placement of advertising on imgbb.com, a website that has been known to host CSAM since at least 2021, according to transparency reports released by the National Center for Missing & Exploited Children (NCMEC). The dissemination of CSAM is a heinous crime that inflicts irreparable harm on its victims. When digital advertising technologies place advertisements on websites that are known to host such activity, they have in effect created a funding stream that perpetuates criminal operations and irreparable harm to our children.”

Production, Distribution, Sale, or Possession of Child Sexual Abuse Material Violates Federal Law

“Amazon’s actions here—or in best case, inaction—are problematic for several reasons. First, the instances of advertisements being served on a website known to host illegal CSAM via Amazon’s advertising technologies violates Amazon’s own policies. As you are aware, the production, distribution, sale, and possession of materials depicting CSAM violates federal law. Amazon’s own policies further prohibit ads from appearing on websites that host ‘illegal content’ and ‘adult and explicit sexual content.’ It remains unclear, however, whether Amazon has ceased its relationship with the website identified in this report, and it is deeply troubling that you have continued to monetize the website for at least three years since NCMEC first identified the website as a purveyor of CSAM.”

Amazon Must Take Immediate Action to Ensure It Is Not Funding Heinous Crimes Against Children

“Many advertisers reportedly cannot readily access page URL-level reports that would allow them to identify which pages their ads have appeared on, including if they had appeared on imgbb.com. Imgbb.com is an anonymous photo sharing website that hosts user-generated content. Without access to the URLs on which their ads appeared, advertisers have no ability to understand whether their ads have appeared on content that violates Amazon’s policies, their own policies, or federal law. It is imperative that your company take immediate and comprehensive action to address this issue and ensure that you are not funding these heinous crimes against children.”
