I'm a computer engineering student. And some of the issues I talk about are about this. The future is completely data mining. There is no other explanation for this. I think Facebook is now the largest data mining site in the world we live in. Briefly, data mining; Data collection in an implicit manner is performed by monitoring the movement of the visitor over the site. The aim is again to determine the relevance of the visitor to the items. We can say.
Large companies from all sectors are trying to acquire or buy the statistics of the data. After that they produce products accordingly. This money is paid too much money. Because it's really more important than you think.
It is really disrespectful and unfair for Facebook to mining over us data.
