The internet is clever, but it’s not always smart. It’s personalized, but not personal. It lures you in with a timeline, then fucks with your concept of time. It doesn’t know or care whether you actually had a miscarriage, got married, moved out, or bought the sneakers. It takes those sneakers and runs with whatever signals you’ve given it, and good luck catching up.
We would never accept this kind of targeting from humans. If you offer someone a drink, they say "No thanks I'm sober", and you then keep shoving it in their face -- that is terrible of you.
We accept the equivalent as a neutral fact of Internet ads. Why?
