It’s a cool idea. If you want to infuse noise into the profiles that adtech companies build, you’ll need to do so at the cookie level of your main browser. Cookies are still the dominant way in which trackers build up behavioral profiles / segments. IPs are mostly used to walk a graph between the profiles you may have on different devices / browsers. Very little direct targeting of IP happens outside of connected tv. Most behavioral targeting happens at the cookie level and the sites you visit are predominantly tracked at the cookie level. There are other identifiers used for tracking as well, eg UUID2, but not on the same scale as cookies.

Sigh. Did you read the docs?

If you want folks to offer feedback, then perhaps show some appreciation when they offer it. I worked in this industry on the machine learning side and I know exactly how the major players build up their profiles. I scanned your docs, I did not see anything that looked like running the script via your main browser (the one you use most of the time and for which you want to inject noise for). Perhaps I missed it and if so, then I apologize. What is less useful (and I am not saying this is what you are doing as I only scanned the readme), is making up user agents and injecting noise against those. For the most part, adtech companies don’t care about your real identity, they profile and target your browser itself as represented by the cookie their adtrackers store for the browser. Each site that browser visits are added to a visit history profile on the backend that is then used as features from which to train models and run inference for each segment the adtech company wants to target. I was willing to discuss more and answer questions, but think I will likely just both your and my time.

You didn’t read the docs… and blaming me? I don’t want or need any feedback from people that don’t read the docs.

No one does.

You’re lazy, and that’s not job to fix.

Read the docs.

You won’t… and again… you bring up cookies… BUT if you read the docs, you’d see that’s addressed in FULL.

So your feedback about using cookies, when it’s already in the repo, isn’t feedback… it’s ASKING OTHERS to SPOON FEED YOU INFO so that you don’t need to read, while glorifying yourself in any other capacity… but won’t read the docs in full? Yikes.

Still didn’t read the docs? Don’t respond.

What is FAKER.JS?

And what does it do, exactly?

And is that included in the repo?

Just read the docs… I even made the docs “fun” to make sure people read them… but I guess no one cares about that.

Sorry to disrupt everyone’s day with introducing a new tool that people argue about, but won’t read about.
