@Ventham , @zhanglin , True guys which makes it very simple!

Trackers like BTN , PTP , HDBits.org , AwesomeHD , GGn etc , wants to control/protect their database and their users by allowing on their site only community friends. Meaning very hard to keep your account there EVEN IF YOU DONATE if is not from their allowed places , BECAUSE they verify every new user..inviting is a very big risk either way!

we can't do anything about it , since are their rules!
