Facebook's trying all kinds of sh*t to get data from you. For example when it says , "You can introduce the location from where you're posting this message" or "Would you like us to register the device you're logging in?"
They would do that anyway.
Using your pictures/videos and friends, they can get your location, age, height, etc.
" Kurumi facebook knows you better than your family "
Maybe true, if you're disscussing things with your friends that you don't share with your familly.
And one more thing, they're selling the data to the
Illuminati. They are the folks who are interested in your data.
