Microsoft released an update on their blog yesterday announcing their new i.e.9 feature "Tracking Protection" which will allow surfers to block tracking cookies and beacons, plus will automatically block a set of known tracking sites

Today, consumers have very little awareness or control over who can track their online activity. Much has been written about this topic. With the release candidate:

1. IE9 will offer consumers a new opt-in mechanism (“Tracking Protection”) to identify and block many forms of undesired tracking.
2. “Tracking Protection Lists” will enable consumers to control what third-party site content can track them when they’re online.

We believe that the combination of consumer opt-in, an open platform for publishing of Tracking Protection Lists (TPLs), and the underlying technology mechanism for Tracking Protection offer new options and a good balance between empowering consumers and online industry needs. They further empower consumers and complement many of the other ideas under discussion.
This is pretty big news for the adult industry, particularly for those affiliate programs that rely solely on cookies for tracking. Thankfully, programs like NATS track by session, IP and cookies, so it won't have an affect on NATS systems. I am not sure if this is the case for other 3rd party affiliate systems, but I suspect it is.
