The scary thought is that their "solutions" page doesn't really offer any good solution. TOR = slow browsing, privacy mode = doesn't really help that much, browsing from your cell phone = hell no...
With regards to the "privacy mode" of most browsers, I think that the feature is mis-named since it mostly refers to the browser's tracking of your activity, not the server's.
I have noscript, but I'm still only one in 47,347. While not uniquely identifying me, I often frequent sites with far less than 50.000 unique visitors.
I'm guessing my non-snow leopard Mac combined with Firefox (that seems to release an update every few weeks) gives me away. Maybe Firefox should stop putting more then major.minor, and certainly not build number, in the User-Agent?
