Do not you follow Facebook because you do not use Facebook? If you go online, then your data is collected by Facebook. Creates 'Shadow Profiles'.
Facebook CEO Mark Zuckerberg was questioned about this in the US Congress. Facebook is not a member of those who are not a member of Facebook? Zuckerberg did not answer the question in detail. But did not completely refuse the matter. He said, Facebook, which collects information about people who do not use Facebook for a long time, need security.
Privacy experts say that shadow profiles can be created in this method of collecting information from online. If anybody logs online after Facebook is logged out, then what do they know about Facebook? In response to this question, Zuckerberg said there are certain issues related to Facebook usage. If you are not logged in, then you can follow the Facebook user. It is necessary to track whether someone is using the Facebook system for illegal use.
The real thing is, whether or not Facebook should be used or not, Facebook collects information about people's online usage habits. Payments for the installation of cookies and pixels for third party websites and mobile apps. Like this, there are share buttons. The data goes away to show the best ads to Facebook through all these. Daniel Kan Gilmour, senior technology officer in the American Civil Liberties Union, said that the Facebook team sent an unsolicited email to the temptation to join Facebook. In this there is a mail address and name of friends and relatives. There is a web bug in that mail, which will open the Facebook server to identify him.
