Is it ethical/legal to obtain journal articles from reddit? My university's subscription is really limited (I come from Lebanon). I never found any paper related to my research or essays using the database that my university is subscribing to; even the basic pioneering papers in business. Yesterday, I started writing my master's thesis and the very basic papers behind my topic cannot be accessed through my university's portal (cannot simply ignore them) and I, obviously, don't have access/cannot pay for individual papers. What to do in this case? Someone here recommended a Reddit page that provides and shares papers upon requests. How legal/ethical is that? The page claims that all the shared papers are based on the concept of fair use.

Eventually, I have 3 options: Follow this way, adopt a bad scholarship behavior by not tracking down original references to check myself (which is out of the question) or I just go home and forget about writing a master's thesis or a literature review because it's almost impossible to access those papers without the help of option 1. As for emailing individual authors, well none have replied so far so it isn't always a practical option as I cannot wait days for 1 particular paper to be received (if any).
Legally, I am not sure --- it depends on the laws on the country as well. Ethically, I don't see anything wrong about it. Academia is about building and sharing knowledge: if anything, I would consider it unethical to put papers behind a paywall.
