I am sorry I can't answer your question: I read many many sources (from big name media to small time bloggers), contrast and apply common sense. I know my limitations to access the 'truth', and I live with that, always in doubt. That said, regarding Facebook, I genuinely never used it really (I have a placeholder account), never used Instagram, never used Messenger, never installed any of these apps on my phone, never log into these web apps on my PC. I use WhatsApp constantly to communicate with friends and family across the world.
