So a bit ago I got an add for “canned rambutan”. I had looked up Rambutan a few days prior after hearing it mentioned 10 hours into the video game Baby Steps. I wasn’t using a VPN at the time and I didn’t have fingerprinting protections active but I only mentioned it to a few sources (according to my browser history) all of which generally are implied to be private.

Which of these do you think is the reason the ad networks know?

  • Wikipedia
  • Startpage Search
  • Duckduckgo Search
  • My ISP
  • Firefox
  • My Firefox Extensions
  • Kubuntu
  • CachyOS
  • The omnipotent algorithm connecting my mentions of Baby Steps with my progress through the game.
  • Does this only make sense if my browser history is incomplete?
  • Maybe I was using DNS over HTTPS via Cloudflare at the time of my search.

Any guesses as to where the weak link is?

    I don’t see ads but if I were to, and despite all my precautions some would be on topic based on my past behavior I would methodically dissect to find out the leak. Namely I would try to automate the process :

    • identify a place showing ads
    • take an action, e.g. search or browser, on a verifiable unique topic (in order to prevent from generic suggestions, e.g medication during flu season)
    • verify if the ads become relevant
    • enable/disable any of the tools used, repeat
