Digiday: Publishers continue to get tough with ad blockers. For a new, six-week test, Conde Nast site Epicurious is serving a pop-up to ad blockers, requiring them to disable their ad blocking software or register in order to continue using the site. “For our users, we found that clear messaging wins and that it was best not to take over the whole screen,” said Eric Gillin, executive director of Epicurious. “I think people tend to scroll down first, so they’ll miss it if you have it too high.”
