You can do a lot to protect your privacy on the Internet. You can block cookies, create elaborate passwords, and only do business with companies with strong privacy policies. But even if you do these things and twenty others, the fate of your information comes down to one thing and one thing only: persistence.
One company clearly has that persistence, and it is no other than Amazon.
The plaintiffs contend that Amazon caused them (and the rest of the class) financial harm by wrongfully selling personal information that has a discernible value in the marketplace. They also allege that Amazon illegally tampered with its patrons' computers, which is generally considered a crime.
Though it's not 100% clear whether or not tricking IE violates consumer protection or criminal laws, it is important to note that the practice is industry-wide. According to a recent study, a large chunk of websites provide false information in order to collect users' personal information. It appears that no matter what you do, your information is never completely safe.
