Sorry mate, I don't agree on that. On the contrary, HDsky has a quite poor reputation among Chinese. Take a look at their local forum Tieba, you'll notice most of the HDSky members are considering abandon this tracker these days. The main reason for this is the staff team. They've caused so many problems before, like banning members for unreasonable reasons. And now, they've launched an assessment during the labor holidays. Many members just don't think this tracker worth the effort to pass the assessment. Now let's talk about the other 2 trackers you mentioned. CCF and TLF are almost dead. These 2 trackers are nothing in Chinese p2p world. Comparing HDSky with these 2 trackers doesn't make HDSky look any better. HDSky should be lvl 1, so are the other 2 trackers. If you have any questions about Chinese trackers, feel free to ask me.

TorrentCCF should go at least one level lower. There's nothing special in it. The encodes of their internal group BDMru don't have good quality due to low bitrate. Other than this group, there's really nothing worth mentioning about this tracker. They've just opened for sign up yesterday - easy to join in.
