There's really no way you're avoiding all the different tracking methods as an avg user. There are literally companies who's entire job is to try and assemble all the data that exists about you, into profiles with your name on it. The more accurately they can do it, the better for them, as they can then resell it for higher value. It's why every fucking thing you do is watched to some degree.

You can watch trends, find out a whole lot about a person if you gather so many thousands of different data points, and then combine them all. Even "anonymized" data very often isn't even close to being "anonymous" and can more often than not be tied back to a single unique individual. Fact is, there's nobody that moves their mouse across the screen quite like you do. Or whatever it may be. There are so many different ways to identify people nowadays.
