HDCorea is the best Korean
HD tracker. They don't have only Korean torrents though, they have English as well.
Many users love their internal releases and it's against the
tracker's rules those releases to be uploaded elsewhere.
The
tracker has an option to choose an English interface, so it's easy for everybody to use it.
Seeding there is not that easy, because the connectivity with the rest (mostly Korean) peers is not so good. But some free
leech torrents and the bonus system make it a little bit easier to maintain a good
ratio.
It's a very rare
tracker, because they open their invites once per year or so. If i am not mistaken it's been more than a year since the last time they opened their doors, so at the moment HDCorea is more rare than ever!
