> You cannot make a connection between these kinds of negative outcomes and Ad Nauseam (and related techniques) because it has never happened...Your entire comment is filled with ridiculous assertions, completely irrelevant tangents, illogical leaps, and pure speculation. None of it lines up with reality.
I clearly can't convince you, but I strongly encourage you to educate yourself if you honestly think none of the things I described have ever happened or could ever happen. Pretty much all of it is happening and/or has happened.

Stores changing prices on a per person basis based on their data?
"For example, ZipRecruiter, an online employment marketplace, indicates that it could increase profits by 84% by experimenting with personalized prices (Wallheimer 2018). Other players, such as travel sites (e.g., Orbitz, Hotel Tonight; DeAmicis 2015; Mattioli 2012), retailers (e.g., Amazon.com, Home Depot, Staples; Streitfeld 2000; Valentino-DeVries et al. 2012), and even grocery stores (e.g., Safeway; Clifford 2012) have also reportedly begun implementing personalized prices for their customers based on individual characteristics."

Other fun ways stores use your data to discriminate against you? They can tell you their return policy is that they don't accept returns or have a very short return window while the next person who walks in the door gets told their return policy is extremely generous. Some even use it to decide how long to leave you on hold, bumping you down to the bottom of the queue when someone with a better "consumer reputation" calls in.
Health insurance rates being influenced by big data? There has been going on for a long time and there's a massive push to increase it.
"Insurers contend they use the information to spot health issues in their clients — and flag them so they get services they need. And companies like LexisNexis say the data shouldn’t be used to set prices. But as a research scientist from one company told me: “I can’t say it hasn’t happened.” (https://www.propublica.org/article/health-insurers-are-vacuu...)

Seriously, all of this stuff is happening. The vast majority of the ways the data you hand over to companies are being used against you happen without your ever being made aware of it, but be assured that your life has already been impacted by the data you've provided and you will be dealing with the fall out of that data being out there for the rest of your life. Adding more data to that pile, accurate or not, will only hurt you.
Google banning Ad Nauseam is not proof that it will save you. Google is in the ad business and it's possible they banned it because they objected to the concept, thought it could have hurt the perception that their data was accurate, had concerns about how it would impact payouts, or any other reason, but it would do nothing to prevent any of the abuses described above and actually opens you up to more risk.
It's not like anyone is throwing out the file they have on you because there might be a mistake in it. Data brokers get paid the same no matter how accurate their data is. Feel free to get yourself flagged as being/doing more and more random things on top of all the real data you give up if you like, but I hope that you'll give it some real thought because it can, is, and will be used against you, and all that data (real or not) never ever goes away.
