you have control, since you can host it on a torrents.csv webserver – however “torrents.csv will only store torrents with at least one seeder to keep the file small, will be periodically purged of non-seeded torrents, and sorted by infohash”. I’d consider that as the nature of the software and not as a trade. If there are torrents which are non-seeded, then it makes sense to purge them. So the software is trade-free.
