You should look into private trackers... I have the same setup for german content (there are no german trackers that have good seeds/content/moderation and api) but for english stuff torrents are still the king if you have the right trackers (ptp/btn/hdb and even 2nd and 3rd tier trackers are all fine). Any listed disadvantage doesn't exist with private trackers, and it doesn't even cost a cent - unlike usenet subscription and indexer.
