Yup. I remember a story about a father coming into Target, furious that his teenage daughter was getting advertisements for expectant mothers. A little while later, he came in with an apology. She was indeed pregnant, and somehow Target’s machine algorithms had picked that up. IIRC, it was brought up in a computer ethics class.

Personally, I think Target as a company also owed his daughter an apology. They in effect invaded her privacy when they told her parents a secret before she was ready to tell them.
