Anyone who cares will be using flash cookies, local storage (or the user storage behavior thingy in IE < 8), etags, etc. Web browsers are full of tiny crevices for tracking tokens to hide.
- stingraycharles 15y agoPremium advertisers generally avoid these kind of practices; basically they don't do business with agencies that use flash cookies and/or browser hashing. Typically, an ad network wants to conform to the guidelines set by the IAB [1], which explicitly recommends against flash cookies, calling them illegal [2]. So, all in all, if something can hurt a brand's reputation among consumers, advertisers generally don't spend their money there. Shady practices like these are among them.

- rabidsnail 15y agoThat only applies to organizations that have a presence in the EU (which probably includes most of the big ad networks, since they have international sales teams). Smaller players domestic to the US don't have the same constraints. Also, it's not just ad networks that do browser tracking.
- rsingel 15y agoIntentionally bypassing user settings to track users might seem like a practical, albeit ethically wrong, business decision, right up to the point that you get caught. Ask Hulu and KISSmetrics, for two. (search "zombie cookies" and those companies names.)
