Well Gotwoot host Aone episodes. Aone-AKingdom were the fansubbers. GSD won't be available from here anymore, probably just the existing torrents in the torrent section, but you should be updated with new releases in it's own section located here

I use Bit Tornado
When you download the client, and there is a couple of episodes in the torrent, goto Details once you have the torrent started and then select the episodes you don't want, and then right click and Select Never Download
