In this case, it would be stealing from a pay service (GomTV). A subscription is relatively cheap at $20.BitTorrent in and of itself isn't illegal. (Actually, BitTorrent is an excellent protocol with many useful legitimate uses. BT just gets a bad rap because of piracy.) As long as the torrent file doesn't point to an illegal or inappropriate download (or illegal or inappropriate download sites, like a certain bay of pirates) and you clearly label it as a torrent, I don't have any issue with users posting links to torrents.
You can, however, watch the first game of every series for free at gomtv.net. The Blizzcon match between 과일존수 and SlayerS_`BoxeR` may be worth watching as well.
