Let’s face it, Reddit’s probably never going to return to what it once was. Most of the subs that haven’t either died or changed their rules are run by "power-mods" that "moderate" well over what someone can manage.
r/Scholar was one of my favourite subs. One of the reasons I was able to contribute so much to that sub was because I made a program that scanned the sub and made a list of the open requests, detecting those that were available on LibGen or SciHub. I had another program that automatically uploaded it to a file hosting platform, made a mirror to LibGen, and commented on the post in question.
With Reddit’s API change, that “bot” (I wouldn’t call it a bot per se, as it had to be run manually) will stop working, it’d take too long to scan the posts to be usable given the new restrictions on the rate limiting of the API. If this community gains traction (and if I have free time to code), I’ll port those programs to work with the Lemmy API.
Although this community is not affiliated with r/Scholar, if the mods there want to port r/Scholar to here and help me moderate, I’ll welcome them with open arms. The more, the merrier.
Thank you for reading my rant/introduction to this community.
You could try Sci-Hub and LibGen. If you don't find what you're looking for, you can always email the authors or other scholars who may have access to the paper you're interested in. A less alternative site would be arXiv, but it just has preprints.
