Yahoo is not happy with its users having adblockers. They are running tests on people to see if they can get them to turn off their adblockers. “This is a test we’re running for a small number of Yahoo Mail users in the U.S.” says a Yahoo spokesperson.
There is no technical reason why the email cannot be displayed. The company is trying to protect its advertising revenue by ensuring people who use its free products can be marketed to — something that using an adblocker prevents.
Yahoo isn’t the first to experiment with detecting adblocking technology, but with them shutting down people’s mail they are making sure people don’t use Yahoo anymore.
My question to you is do you think this is a good idea? Does Yahoo have the right to lock out their own users just because of ad blockers?
