Hi Dan,
And that is only part of it, just fire this site up and have a look here then:
www.cookiechecker.nl -> for cookies and third party tracking
Or use this extension: Collusion for Chrome to see all the interrelated patterns between sites and tracking sites....
And then we did not discuss the tiny little web beacons, they become visible via web bug detector, an extension for google chrome also.
And not all of these trackers are respectable trackers as on the avast forums with it's minimal tracking, we have an 80 out of 100 score where privacy is concerned.
No, dan, there are obscure trackers bordering on being malicious, like admeld and the like, and there are malvertisers, trying to get gains
from re-directed clicks, and it is getting all the more stealthier and hidden and under the hood of the browser, and the results will land on a desk near you,
but they won't pay you for it. That is a real pity, isn't it?
