便便分析应用据称向 AI 训练出售用户粪便照片
reddit 上的一则广告推销了一份包含 25000 名 poopcheck 用户 15 万张粪便图片的数据库，用于出售给 ai 公司。
a reddit user identified as the developer of poopcheck advertised the sale of a database containing 150,000 labeled stool images collected from 25,000 users. the seller marketed the dataset for machine learning training and cancer studies, despite the app's 'privacy first' branding and explicit claims that no data is collected. while the app store listing asserts data encryption and retention policies, the internal terms of service reportedly allow for data aggregation. this exposes a significant gap between consumer-facing privacy assurances and the actual data harvesting practices of niche ai applications.
