> the data broker Acxiom even placed me in a category called “Alcohol at Home Heavy Spenders” (was it because I went shopping for a birthday party at home?), and a company called Affinity Answers thinks I have a social affinity with the consumer “Baby Nappies & Wipes” (very, very wrong).
We tried a few of these services that match site visitors to segments/categories at my prior job. None of them worked all that well. I suspect part of the issue is that their customers ask them to create highly specific segments that aren't possible to infer about people, at least not without a huge amount of noise.

I'm curious if these types of firms use other data (browser profile? IP address?) to link data into a single profile across multiple browser sessions.
For example, if I wasn't blocking ads/scripts but I still had cookies set to clear on browser exit, would their gathered data only apply to that session or get added to some overarching profile of me as a user?
I'm less concerned about ads being tailored to things I did in the current session and more concerned about the longer-lasting profiles built up over time by credit card use, browsing history, and other data points. Seems like more potential for abuse than if they're depending on something as short-lived as a tracking cookie.
- Safari is ahead of the pack with its ITP 2.
- ad blocker extension is a must
- private browsing windows gets rid you of tracking cookies (incognito in Chrome, but Chrome is made by an Ad company .. :)
- VPN hides your IP
I think restricting by law their core business model would be not an easy task, it is life or death question for tracking companies like this and FB/Google.
Sometimes locking your doors isn't enough.
And you need to be careful about your VPN. Make sure it's in an area that doesn't have an agreement with the NSA, and even then you still need to be very careful.
For iOS Safari, if you install Firefox Focus, you can enable its blocker in Safari. Plus Ka-block
also in Chrome it's not possible to block things like sending URLs back to base for safebrowsing (like Firefox)
