@imadyoucef Hey mate , about your questions :
- CGPeers : as Yusuke told you , got plenty of applications options related to 3D / Visual Effects / Computer Graphics / Design.
- BrokenStones : Specialized in Mac Apple World , got almost all mac content.
- For Applications for Win softwares , IPTorrents got many as well.

If you're asking for an open site , i dun know & we don't RECOMMEND open trackers for sure . That's all !
