"Do Not Track" had a lofty goal: You know, it's a simple check box in every web browser that tells the sites you link to not to follow you.
The operation seems to be using too many, but there is a problem: Websites are not interested.
You should know that the "Do not Track" option does not prevent you from following the websites. It just sends a message every time you link to a webpage asking it not to follow you. But most web sites ignore the message, and that is not going to change. At the moment there does not seem to be any "penalty" for web pages ignoring Do Not Track, so why respect it?
"Do not Track" has been around for years. The option is used by Google Chrome, Mozilla Firefox, Apple Safari, Edge and Microsoft Internet Explorer. You can tick the box if it makes you feel safer but it doesn't really help you online. It is completely misleading.
The truth is that Do Not Track is used to track people. If you've turned on the feature, you give an additional element to advertisers who see that you are interested in security and serve you privacy-related ads (for example).
So, as shown, this checkbox is totally useless. Such as he remarked DuckDuckGo, Apple removes this option from Safari and we expect other browsers to follow Apple's lead. As W3 says, DNT request header support has stopped on 17 January of 2019.
"Do not Track" is said to act as a placebo and mislead internet users.
The story about Do Not Track was started by Microsoft, which enabled Internet Explorer 10 by default, causing most web sites to ignore it. The funny thing is that Microsoft itself never respected the setting saying that "Because there is not yet a common understanding of how DNT is interpreted, Microsoft services are not currently responding to browser signals."
