Yahoo recently announced that they would stop honoring Do Not Track requests. This technology works to keep sites from tracking users’ activity but it needs the third-party to agree that they would honor these DNT requests. The reason behind Yahoo’s decision is that they “fundamentally believe” the best online experience is a personalized experience. They would prefer their users use the privacy tools the company offers on their platform. It is going to be a bit tedious to tinker around with your settings on Yahoo but to continue using their services this would be your only recourse at the moment.
