I’m not an expert on the subject, but a discussion elsewhere reminded me of some tests related to tracking and fingerprinting. I believe it’s a nice starting point if you are interested or want to show others how much information can be used to track them.
Growing up, your IP was the great identifier, and I’m old enough that it might have been true for a good chunk of time. Hiding your IP is still important, but most companies don’t really care about you as an individual. Actually, the fact you are hiding you IP is just more relevant information to put you in the most adequate group. At the end of the day, I assume you are unique just because they have enough information to create a group with you alone.
I am very unique… solely based on the the referer 🤣
