TPB is pretty poor for anime TBH. AB, BBT, Nyaa, XDCC and direct translator websites are much better for anime.
HDT isn't really that great. Try BTN for TV, PTP and TC for Movies and PxHD for both. AB for Anime. And be careful while handing out invites. If your invitees cheat/leech irresponsibly/otherwise screw up it can affect your account adversely too, leading to revoked privileges, warnings and bans for you along with your invitee. AB has open application which can be passed easily. Just requires you to know about torrenting and actually be interested in anime beyond the main shounen stuff. PxHD too, but they require you to have accounts with a good standing in other trackers. Try getting to PU+ on trackers which will give you access to internal invite forums that allow you to enter even more trackers.
