Shameless plug of my gokkun collection megatorrent...
I tested (and it works) only on uTorrent 2.2.1 in default settings, what version are you using?

This is a curated selection of facebang/gokkun/r*** plus schoolgirl/lolicon.
Studios:
Dogma
Moodyz
Waap
Idea Pocket
Knights Visual
Minimum AV
IB Works
Everything censored.
The gallery is quite large (120MiB), you can download it here as a zip for local viewing...
Top hentai studios/character designers of the past decade. Widely known series like Accelerando or Black Bible are left out. Most, if not all, is the most popular stuff on nyaa (hihiko123..), except this torrent is subbed and sorted according to studio/series, not raws.
Everything is censored...
