I noticed quite a few hits on my various domains from proxy servers at Marketscore.com, so I decided to do some digging. According to articles at Wired and Slashdot, Marketscore is a marketing and trends firm that installs tracking software on your machine that basically acts as big brother and watches every single Web site you to go including encrypted sessions.
Marketscore monitors all of your Internet behavior, including both the normal web browsing you perform, and also the activity you may have through secure sessions, such as when filling a shopping basket or filling out an application form that may contain personal financial and health information. Marketscore’s proprietary and patent pending technology allows us to see the details of secure pages while protecting such content from parties other than the site to which you are connected.
And people happily consent to this! Be afraid. Be very afraid.
