Disney, Ustream, SodaHead, Warner Bros., and a number of other websites are spying on kids’ Internet use, according to a lawsuit filed recently by a group of parents and their children. The suit accuses ad widget company Clearspring Technologies of enabling these sites to track kids all over the Internet, and not just on Clearspring partner sites, leaving them in violation of numerous federal and California state privacy laws.

According to the complaint, each of the Clearspring affiliates independently and knowingly authorized the company to track users, even on non-Clearspring affiliated sites. A Flash-based tracking cookie was allegedly installed by the affiliate sites without users’ knowledge, and would recreate itself by digging into the Flash storage bin for the same user information if deleted. Essentially, users who were trying to remain privacy-conscious by regularly deleting their cookies were not able to rid themselves of the cookies deposited by Clearspring.

From there, the defendants allegedly collected personally identifying information about their users in order to sell the data, which includes video viewing habits, gender, age, race, education level, geographic location, sexual preference, what the users like to read, home address, phone number, health condition, and more, says the lawsuit. The parents behind the lawsuit cited a recent study out of UC California-Berkeley about Flash Cookies and Privacy, which found that certain Flash cookies would respawn when deleted—without any notice to or consent from the user.

I delete all Flash cookies but I didn’t realize that some were able to “respawn.”
