I had one at 62% for years I watched peers come and go but never lost hope. Today it's at 99%. All I'm missing are some padding files so basically 100%.

There's me and one other peer who seems to be willing to seed until the end of time. My ratio keeps climbing so I assume someone somewhere is thankful

250KB of one of the rar parts

Ouch!

I’ve replied this to another comment already, but it is probably this:

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.

It absolutely could be brute forced, we litrally have the hash of the chunk. I've thought about it before too, if one seeder is constantly giving, or refusing to even give, the chuck because of the hash mismatch, odds are it's only a bit flipped somewhere.

Another option that I've done before is find the file elsewhere, and switch it out. Seed for a long time then, you weren't the only person at 99.9%.

The problem is there will be multiple solutions that result in the same hash (collisions), but only one of them will be correct

And it would take an extremely long time to find them all, I don't even think a modern GPU could do it in a lifetime

Stupid protocol can't send the big file if the small file next to it is missing. Gotta have the whole block.

Why do this? Somebody might need those files, and they only cost you a couple kb of space

Trying to get an audio copy of the Witcher prequels here

All the mainline books were easy, but these last couple have been a pain.

try soulseek for those

Whatttt xD

If no one shares with usenet, there's nothing there to download.

I'm part of several closed usenet communities and torrent communities. The usenet ones feel much more like real communities than the torrent ones. The quality and support is also much better.
