Do you actually use torrents day to day? I have a strong suspicion that nowadays most people in developed economies who might be interested in TUIs use private trackers, as they're much safer and usually much better curated. However, that means that a) ratios are usually enforced, you have to keep seeding b) DHT and PEX are disabled and explicitly forbidden. Which in turn means the features you are describing are anti-features, especially considering the rise to *rrr-family of tools aggregating centralised private trackers, and relative unpopularity of DHT for discovery. Without curation and entry barriers open systems like DHT are only going to get spammed and/or get the swarm members DMCAed by RIAA and friends.

Edit: slight rewording

I do use torrents daily, and I don't use private trackers because I subscribe to the idea of shared content available to everyone if the cost is nil. There definitively is spam, but it's not kazaa- or emule-level of spams: it's easy to find correct content as soon as it's not too obscure. With a fast enough connection, you can have a >1 ratio in a matter of hours at most, so your visibility is not very long. YMMV, of course.

I don't think seeding for hours is conductive to long term retention. For context, in private tracker land it's normal to seed an obscure arthouse movie for years, being an only seeder and getting it downloaded maybe five times. Which reminds me that the cost is not really nil, as you have to pay those electricity bills and depreciation to keep it available. Curation is not free either.

I have lost hope that public torrents can serve as a good availability system. The issues are not technical but "societal", ie what rules do we collectively follow, to make content available. Private trackers are perfect for this specifically because they have a way to nudge people into re-sharing poorly seeded torrents. Bittorrent helps do that, but any technology can.

> being an only seeder and getting it downloaded maybe five times

I haven't seen/conducted a thorough study, but I believe that a ratio of 5 helps content be alive for a longer duration, even if imperfect, taking into account 1 or 2 or those 5 that will disconnect and stop sharing. Everyone should target this ratio. That's why I'm ok seeding for hours as long as I hit that number, but for more obscure content I might be seeding it forever

> Which reminds me that the cost is not really nil

True, nothing is really ever nil. What I meant to say is that the cost of distribution is nothing compared to the cost of production.
