Over six months, we tracked the appearance of child sexual abuse material on X. We found images from the National Center for Missing and Exploited Children's database, which is considered one of the most highly vetted and which many tech companies block on upload. www.nytimes.com/2026/09/11/t...

We also partnered with the Canadian Center for Child Protection to analyze Grok images produced during the nudification episode in Jan. It found images of known CSAM victims that were modified by Grok, and new CSAM that it created in response to requests from users. www.nytimes.com/2026/09/11/t...
When we presented our findings to child safety experts, they were shocked that we were persistently finding NCMEC images. Even though X said it reported 1.3 million images to NCMEC this year, some were clearly slipping through — X did not answer specific questions about how it blocks abuse material.

This reporting was difficult in many ways. It is a technical challenge. It is hard to get buy-in for a story about a subject that is so horrific many people would prefer to not examine it. It is also emotionally difficult. Throughout it all, @mhkeller.bsky.social was a steadfast reporting partner.
