The only way to taint your behavioral data so that you don’t get lumped into a targetable cohort is to behave like a manic. As I’ve said in a past comment here, when you fill out forms, pretend your gender, race, and age is fluid. Also, pretend you’re nomadic. Then behave erratic as fuck when shopping online - pay for bibles, butt plugs, taxidermy, and PETA donations.

Your data will be absolute trash. You’ll also be miserable because you’re going to be visiting the Amazon drop off center with gag balls and porcelain Jesus figurines to return every week.

Is there a similar tool that will “poison” my personal tracked data? Like, I know I’m going to be tracked and have a profile built on me by nearly everywhere online. Is there a tool that I can use to muddy that profile so it doesn’t know if I’m a trans Brazilian pet store owner, a Nigerian bowling alley systems engineer, or a Beverly Hills sanitation worker who moonlights as a practice subject for budding proctologists?

Have you considered just being utterly incoherent, and not making sense as a person? That could work.
