Internet Explorer 9 Tracking Protection Lists not all created equal

Tracking Protection is Internet Explorer 9's kicked-up privacy protection system, a sort of evolution from IE8's InPrivate Filtering. And while there are now four lists posted on Microsoft's official site, they're not all designed to function the same way. ZDNet's Ed Bott took an in-depth look at all four, and what he found may surprise you.

One list -- provided by TRUSTe -- does very little to block potential privacy issues. In fact, it's designed as more of an allow list, making sure that sites on the TRUSTe list have access to data which can personally target you. Have a look at the list in plain text [link] -- all of those +d domains are being allowed. At first blush, it looks as though any site which has a TRUSTe seal has been greenlighted, from to to every Windows Live domain you can think of.

This may not surprise you, of course, if you know a bit about TRUSTe. The California-based company has been providing digital privacy certifications for websites since 1997, and has posted seals on pretty much every big-name site you can think of: Facebook, Apple, Microsoft, Yahoo!, IBM, and eBay are just a few. So apart from knowing that TRUSTe's list gives the all-clear to any sites it has previously stamped, it's also worth knowing that TRUSTe received some heat in the past following a report by Benjamin Edelman, who found that sites with TRUSTe certs were 50% more likely to violate privacy policies than those without.

If you're hoping to use an IE9 Tracking Protection list for actual privacy protection, we'd recommend going with EasyList -- which performed very well in Bott's testing.
