oh, right, if i ever post links that lead to websites like anna's archive, libgen, sci-hub or zlib, do not enter them
while completely legal for personal use in my country (including sharing the downloaded files with friends or classmates), these sites are very dangerous, offering access to very expensive research papers to everyone without any fees. as a result, they're facilitating the unrestricted flow of knowledge and making an effort to bridge the educational gap between the wealthy and the poor. BEWARE
