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?
one of the sites you looked at while looking up rambutan? no vpn too, if a page you looked at was served ads by an ad provider they could track you with your ip, as well as assosciating you with a unique fingerprint since you dont have fingerprinting protection. if you only used wikipedia, there is a second rambutan season in some places from november to january, so its possible that they (the rambutan or fruit processing and agricultural industry) are just trying to pick up sales ahead of the season.
if you have sus extensions too.
