You have a unique "passkey" in the torrent that you download, and the tracker won't let you connect without it. I wouldn't try to cheat it, or you'll likely end up banned. Trackers have scripts to detect tampering.
Not to mention its not a huge scene. If you get black-listed, you might have a hell of a time getting back in to decent trackers if the admins share info on known blacklisters
It's possible but eventually you will get banned I remember a torrent client that let me multiply my seeding by 100 I did use it back when file list was a thing.
That said I can't ever remember seeing anything similar since.
There is no reason that this should be possible on a private tracker. Public trackers, yes. Private ones need user authentication to let you download anything so it's trivial to track the ratio at the same time.
Filelist org while it no longer exists was a private tracker and I can absolutely say the cheating ratio client completely worked.
While I'm not proud of keeping myself ratio balanced that way (I had a very tiny upload compared to download) I can absolutely say a hacked uttorrent client kept me well above ratio at the time.
It worked well although I kinda glad I haven't seen similar mods sinxe
This is the first time I ever hear of Usenet... read a little... but honestly sounds freakishly scary... torrents are anyway filled with malware... and now we have to trust a centralized source for files?
Do clients that use Usenet verify public torrent file hashes? How is security handled such that I know the files aren't infected compared to whatever the same torrent offers?
The files on Usenet aren't centralized, they are shared among all Usenet servers, each of which chooses how long to keep that file, usually on the order of 3000-5000 days. Think of it as a torrent uploaded to every single tracker in existence. No matter which Usenet provider you use, you get access to the same files as everyone else, just like your ISP gives you access to the same internet as everyone else. I don't know if it's possible for your Usenet provider to infect files, but I don't think that it is likely they would do that. Running a Usenet service isn't cheap, and something like that would ruin their business, even if it is possible, which I don't believe that it is.
There is definitely a chance you'll download something that an uploader infected with malware, same as torrents. In that regard, use common sense, just as you would with any torrent, and check the comments on the indexer you use.
Just setup a seedbox, man.....why you gotta cheat?
If you don't want to do that, switch to usenet or public trackers with a VPN. Private trackers are small and require seeders to keep torrents alive. That's why they incentivize it.
