How to block companies from following you on Facebook

When we use applications or use any website linked to Facebook, all personal information is saved to track you including your email address, phone number, activity history or place live and work. And no one knows what their personal information will be used for. The best way is to check which company is accessing personal information and limit it.

When accessing an application on Facebook, or logging in to a website via a Facebook account, we unintentionally reveal all personal information to advertisers. And of course you will fall into the sights of companies and will be monitored anywhere. This will not be wanted when dozens of companies are watching you, but we don't know who they are.

However, it is not difficult to check the list of companies or applications that are tracking your Facebook profile. In this article, Network Administrator will show you how to check which ad company is following you and correct it.
