adnauseam is seriously a terrible idea. It's actually dangerous. The idea that you can somehow trick advertisers by polluting your dossier and making it useless to them after filling it with random data is fundamentally flawed.
Every scrap of data collected about you will be used against you. It doesn't matter if it's accurate or not, nobody cares if they data they have about you is accurate, data brokers will happily sell your personal info to anyone even knowing full well that it's got inaccurate and conflicting info in it. Many won't even know because the process is entirely automated.
By automatically clicking on ads and "expressing interest" in random things you're just filling your dossier with ammo which gets handed to others to fire at you. Every random thing you add to your permanent record is one more thing that can only hurt you.
You cannot know what will prejudice someone against you. Maybe one day adnauseam decides to click on something that gets you flagged as having a certain political view, or having a certain sexual orientation, or being an alcoholic, or having a mental illness, or being at a certain income level, or belonging to a certain religion, etc. One day that exact data can cause you to get turned down for a job, or for housing. It can mean that a website charges you more than what your neighbor pays for the same product. It can mean your insurance rates go up next year.
You will never be told when it happens or why. Your health insurance company isn't going to tell you that they raised your rates because you (adnauseam) clicked on too many fast food ads last quarter. You're just suddenly getting a higher bill. Your auto insurance company won't tell you that they raised your rates after you were clicking ads for DUI lawyers, but suddenly they and every other insurance provider you try are quoting you higher monthly prices.
If your browser extension decides to go click on ads about abortions you could even end up being hauled into a texas courtroom and having to defend against charges. Sure, you'd get them thrown out eventually. Probably. But it would still cost you a ton of time and money and stress. The information in your dossier can get you targeted, harassed, or attacked by extremists. It can get be used against you in court rooms. It can get you investigated by three letter agencies. It can be used to impact your 'secret consumer score' or consumer trustworthiness rating.
The information being collected about you is sold to companies, employers, activists, extremists, and law enforcement. That data never goes away. It follows you for the rest of your life and will be used against you in ways you'll never be aware of and cannot today imagine. Filling your dossier with huge amounts of content (random or not) is dangerous and only increases your risk for zero benefit.
