i know there's a bunch of ways to track people without cookies (supercookies, browser fingerprinting, etc.), but is there any evidence that they're being deployed by google or any of the big western advertising companies?
We used it mostly to try and track malicious users (banned users, etc.) but it's still tracking nonetheless. It was reasonably effective.
I'm sure a company of Google's size and sophistication has many more advanced methods than we did.
