The data dump on the Internet Archive says that signing in is required to access the files; however, even after signing in to the site, I only have access to 5 files (mostly metadata files), while the rest are marked as unavailable for download. What's the reason for this?
In addition, the torrent file says unavailable for download, but I was able to download it by copy and pasting its address in the browser, while another file (e.g., the Posts file for Stack Overflow) simply gives a "403 forbidden" error.
