Many times, people quotes studies that are either hidden behind a paywall or some extremely greedy materialistic site like John Wiley & Sons.
Or even worse, many times I quote a study and I feel a bit obligated to provide a link for it as an answer.
One member told me once:
That link isn't to the study. This makes it hard to check whether the study took reasonable care to avoid confounders
When I replied saying that it is not my job to provide links to studies he said:
Ah, but on this site we want to see the references to the authoritative study, preferably as a link so we can check it quickly.
With my robust search skills, and having an free full online access to the largest library in town (academic papers, journals, studies, books), I can easily find full access to studies, so I started exporting a PDF file and uploading it to my Google Drive.
While I might not be allowed to do it, sometimes it is necessary and help other members see the content.
So I started uploading full studies to my google drive and linking them.
I don't really care if it might upset the publisher, the publishers usually are businesses (like Wiley) or universities (like Stanford) with billion dollars in assets and net worth. If they think their rights are violated they'll have to go to the process of sending a DMCA request to Google, then Google would take appropriate action.
Also, the moderator's job is not to verify if links violate a copyright law.
My only concern, is that I don't want this to cause problems on skepitcs.se.
