Has this ever happened to you?

You are browsing the Internet and maybe you look at some items and then it seems every where you go you are seeing the same things or related items that you just looked at. Maybe you abandoned a shopping cart or changed your mind about the purchase. Maybe you started filling out a form and stopped in the middle of it. They can’t possibly know what you typed, right? Or can they?

In an article by Motherboard.com, they cite a study done by Princeton University about boundaries. Or rather “No Boundaries.” How do you think Pinterest or Facebook or other social media sites get the information? There are sites such as FullStory that allow website owners to capture every keystroke a user makes. They use “session replay” scripts to capture what the customers are doing on their sites. You can see some of the major companies who use fullstory.com here.

Now more than ever it is important to read websites’ terms and conditions. They may collect things like medical conditions, personal data, credit card info. Passwords may even be “accidently” included in the data.

So what can you do? Run AdBlock Plus in your browser. According to the Princeton study, AdBlock has been updated to block all these scripts, thanks to the study.
