Deleting Facebook accounts will not stop it from tracking you!

The voices demanding the deletion of Facebook accounts in the last period since its recent disclosure about the loss of data profiles of users of Cambridge Analytica. Many public figures and celebrities who have a lot of followers on Facebook have announced their desire to remove their Facebook profiles and pages (although some have not already done so, such as Elon Mask, CEO and founder of Tesla Electric). Facebook management now recognizes that it has other ways to track previous users of the platform. Deleting Facebook accounts will not stop network tracking for users after removing their accounts, and even for non-users who have not already created cookies.

Mark Zuckerberg, chairman of Facebook, testified before the US Congress last week and tried to evade questions about whether the network was collecting non-user data as well. But he admitted - when pressed - that the network collects data that did not subscribe to the network and did not accept its terms.

Facebook responded to the blog after Zuckerberg's testimony on how they obtained the data and also identified where to get the data. The primary source of non-user data is websites and apps that use network services:

"When you visit a site or use an application that uses our services, we receive information about your visit even if you are not logged in or do not have a Facebook account. The reason is that sites and other applications do not know who Facebook users are and who are not users. "

This means that if you visit a site and click the "Like" or "Share" button, this site is likely to send data about your visit to the Facebook network.

The network also receives user data when they log on to a site or application using the network login data, sometimes showing the user "login using Facebook" in some locations.

Surprisingly, network specialists say Facebook is not alone in doing so. Many companies offer these types of services and also get information from the applications and sites they use. They pointed out that Twitter, Pinterest and LinkedIn have buttons similar to Facebook's "Likes" and "Share" buttons to help users share what they want on their networks. Google also has the Google Analytics service, the famous Analytics, Amazon, Google and Twitter provide login services using the user account on them. In the end, all these and other companies offer advertising services and most applications and sites send the same user data to many companies each time they visit the site or application.

The process of sharing user data is often aimed at refining the ads submitted to him. By specifying the location of the user, determining the sites he visits and the things he may buy through shopping services and other information, companies can provide the most appropriate ads to the user. User data leaks and networks win large amounts for service to advertisers.
