I dramatically extolled the virtues of "Corinthian leather" during a dnd campaign and started getting advertisements within 24 hours about Corinthian college. I don't need another degree, I graduated 10 years ago. I'm thousands of miles away from their campus, I live in a cabin in the woods.
This happens all of the time in our household. I'm seeing ads for things I never talked about, but are related to my wife's searches because that's as close as they can target.
I was at work one day and my co-worker was dribbling a basketball in the office just talking to me, and I happened to mention that I could ALMOST dunk but never actually got it in no matter how hard I tried. I open my phone and see an ad for "learn to dunk in 30 days guaranteed."
I don't care about basketball. Haven't watched or played it regularly since the 90s, never search anything related to it.
So am I and no oce at this point can convince me otherwise, it's the singular "conspiracy" I believe.
The amount of times I've had the same thing happen is staggering to the point I can't dismiss it as a mere coincidence anymore.
