1. Ratio maintenance is easy because of freeleech, bonus points, and seeding rewards
- “They often designate items as 'freeleech,' which means that downloading does not cost you ratio, but uploading still credits you.” — flurie
- “Almost every private tracker has a bonus point system: you are awarded bonus points for seeding… and can exchange them for upload credit.” — sdthjbvuiiijbb
- “In practice, my 'real' ratio … is 0.2, but after my credits it is 7.0 (far above the recommended 2.0). It's basically impossible to not meet the ratio requirement… if you're putting a small amount of thought into it.” — frenchtoast8
2. Trackers employ soft caps, seeding‑time rules, and point economies to make ratio largely symbolic
- “They tend to have a soft cap, so the automated warning systems don't even start until users dip below 0.9‑0.95.” — flurie
- “Some trackers solve this by having certain torrents not count towards your download, only towards upload… you need to seed a torrent at least X amount of time after finishing it.” — pferde
- “I know from using myanonamouse that you only need to seed for about 3 weeks after downloading… they artificially grant you an upload amount of whatever you downloaded.” — haaz
- “On many of the best trackers the ratio system is essentially symbolic.” — sdthjbvuiiijbb
3. Cheating or gaming the ratio is possible because detection is weak; the system leans on a social contract
- “Due to how BitTorrent tracker works, you can cheat your reported upload… many private trackers have little to no custom dev done to them.” — maeln
- “The proper way to cheat is to not leave a trace on the tracker… it's called 'ghost leeching.' … unless they can detect a pattern.” — binaryturtle
- “It isn't hard to work out that it's impossible for a forum to maintain a true 1:1 ratio based solely on reported byte counts… you must have some sort of mechanism for acquiring 'ratio' other than actually uploading something.” — jerf
