Friends: Have you taken the Sci-Hub survey (on Survey Monkey)? It takes less than two minutes and one is not at any risk of being identified. You might wish to recommend the survey to your users. Physicists and mathematicians, I presume, may not feel compelled to use Sci-Hub. They get most of what they need from arXiv. Do you know Sci-Hub users are not limited to the developing world? "Some critics of Sci-Hub have complained that many users can access the same papers through their libraries but turn to Sci-Hub instead—for convenience rather than necessity. The data provide some support for that claim. The United States is the fifth largest downloader after Russia, and a quarter of the Sci-Hub requests for papers came from the 34 members of the Organization for Economic Cooperation and Development, the wealthiest nations with, supposedly, the best journal access. In fact, some of the most intense use of Sci-Hub appears to be happening on the campuses of U.S. and European universities." How many among your users know and use Sci-Hub? India, along with China and Iran, is among the three countries downloading most articles. Best.
