“At least one of those images could be considered Child Sexual Abuse Material (CSAM) because the daughter’s genitals appear to be visible,” the filing says.

The post garnered over 204,000 views before images were removed from a second version of the folder, the letter says.

The filing asks whether the images were removed because someone “realized that it was ill-advised (and, in the case of the potential CSAM image, illegal) to share these images with the world.”

“How many people accessed and downloaded the intimate image, and each of the other images of the child, including one in which her chest is exposed?” the letter demands.
