The internet is watching you. It listens to you through Facebook Messenger. It reveals your location with every Tweet you send with a picture. It keeps your forgotten updates, your teenage blog and your cringey MySpace selfies. It knows what you like, what you buy and who you’re friends with. It might also know where you live.More and more it feels as though using the internet is like inviting a stranger into your home.
