Description: An image dataset, NudeNet, used to train systems for detecting nudity was reportedly found to contain CSAM images, including material involving identified or known victims. According to the Canadian Centre for Child Protection, the dataset had been widely downloaded and cited in academic research prior to discovery. The images were allegedly included without vetting, exposing researchers to legal risk and perpetuating harm to victims. The dataset was subsequently removed following notification.

Variants
A "variant" is an AI incident similar to a known case—it has the same causes, harms, and AI system. Instead of listing it separately, we group it under the first reported incident. Unlike other incidents, variants do not need to have been reported outside the AIID. Learn more from the research paper.
