When you go into the privacy settings on your browser, there’s a little option there to turn on the ”Do Not Track” function, which will send an invisible request on your behalf to all the websites you visit telling them not to track you.
Yahoo and Twitter initially said they would respect it, only to later abandon it. The most popular sites on the internet, from Google and Facebook to Pornhub and xHamster, never honored it in the first place.
From the department of irony, Google’s Chrome browser offers users the ability to turn off tracking, but Google itself doesn’t honor the request, a fact Google added to its support page some time in the last year. […] ”It is, in many respects, a failed experiment,” said Jonathan Mayer, an assistant computer science professor at Princeton University. ”There’s a question of whether it’s time to declare failure, move on, and withdraw the feature from web browsers.” That’s a big deal coming from Mayer: He spent four years of his life helping to bring Do Not Track into existence in the first place.
