"We know what kind of porn you see," said Google and Facebook, from where you are probably reading this article. These two companies are so powerful that they know almost everything about you, including the kind of pornography you consume.

According to a recent study, it was discovered that Facebook, Google and Oracle monitor the type of pornography that is consumed through a tool called the WebXray, which tracks the data and sends it to third parties.

Even if you use the "incognito" option, which promises not to be preserved and the history is not updated, the aforementioned companies still track it. "Incognito" simply means that data is not stored on the user's computer.

All pages that Sara misses visit, observe, track, and sign up. Often, they are sent to third parties who can well be informed about Sarah's sexual orientation if they want through the pages she visits. These data are used to build a customer profile and to market more efficiently different products.

The study, which analyzed 22,484 pages of sexual nature, was conducted by researchers at Carnegie Mellon, the University of Pennsylvania and Microsoft, competing with Google and Oracle.

Google has trackers in 74% of the pages, Oracle at 24 and Facebook at 10%.
