This is not a SFW instance. NSFW communities will be tagged, and efforts will be made to keep SFW communities clean, but proceed at your own comfort level.
Most of the time it is due to Cross-seeding and additional or manipulated files.
I.e. the 99% torrent contains an additional file like an nfo or srt that was not in the original upload on a different site.
People cross-seeding the original torrent don’t have that file, so you can only get 99% from them. And if the uploader of the torrent with the additional file stops seeding, there’s no one you can get it from.
Or if it is stuck at 99% without additional files, it’s possible that the file that was uploaded was manipulated. Stripped UID or other metadata that was changed. So there will be a mismatching piece that you can’t get from the cross-seeders. And again, if the uploader stops seeding the manipulated file, you can only get 99% from the cross-seeders.
