AI Poop Analysis App Sells User Database of 150,000 Stool Images to Highest Bidder

A few weeks ago, a post on Reddit’s r/DHExchange, a subreddit dedicated to trading large datasets, caught attention with the title: “I hoarded a large database of something valuable, just not what’s [sic] you expect…150k stools images.”

The post was made by a user named Ill_Car_7351, who revealed a database of poop images collected from an AI-powered poop analysis app he had launched years earlier. The dataset included 150,000+ labeled and classified stool images from approximately 25,000 different users.

In his post, Ill_Car_7351 wrote:

“I’ve got 150k+ labeled and classified images of 💩 from roughly 25K different people. Jokes aside, I know there’s a lot of value in it (hard to obtain, useful for ML [machine learning] training, cancer studies etc) but not sure on how to move about it. Feels like I’m sitting on a pile of shi..ny coins but can’t find who wants them.”

He also emphasized the rarity of the images, stating he was unsure how to price the dataset. The comments section erupted with reactions ranging from disbelief to disgust:

• “When I was 5 the teacher taught me how to read. I now regret that happened.”
• “What in the fuck.”
• “How to delete someone else’s post.”

After messaging the poster, the author of this article began exploring the Internet of Shit—a term used to describe the unsettling intersection of technology and absurd or invasive data collection—specifically the underground market for highly sensitive user data harvested by apps and sold for AI training.

The PoopCheck App: AI-Powered Stool Analysis

The database originated from an app called PoopCheck, developed by the company Soft All Things. The app claims to use AI to analyze stool images and provide users with a “daily gut health score.”

According to the app’s description:

“Our AI analyzes your poop using the Bristol Stool Scale and advanced pattern recognition. Get insights on consistency, color, shape, and what they mean for your digestive health.”

The Bristol Stool Scale classifies stool into seven types, ranging from “separate hard lumps, like little pebbles” to “watery with no solid pieces.”

Community Features and User Engagement

PoopCheck includes a community feature with 151,317 “shared stools” at the time of reporting. Users can share images of their stool for community commentary and earn points for participation. However, sharing is not automatic—users must opt in when uploading a photo.

Posts in the community include titles such as “play dough,” “Concerned,” and “Dealing with this on and off for the past 3 weeks.” Some popular posts feature users speculating about health conditions like parasites or colon cancer, with comments suggesting remedies such as ivermectin.
