You all Programmers/Coders don't understand what did you make by just copying design. rarbg HAS access to 0day FTP servers so most of the releases that hit the SCENE mirrored in minutes. They have bots for P2P too mirror BtN and BHD. I never download a single release but they re-encode the x264/TV files to smaller size. So if you want to make similar to rarbg do not scrape open source magnet trackers build up a system like above.

If I'm not mistaken the Chinese torrent trackers goes offline several days in a year. The police "fight" with piracy but the trackers are tipped off before the operations so that copyright holders can be mitigated by doing that.

I know there exist request topic but I'm looking more than 500 releases so asking to one user not a good behaviour. I'm in that forums too but its the same. Only dc++ left as you said its so hard to get in private hubs.

I'm member of RED so finding flac not a problem. I asked for older SCENE releases that might be filled with requests on these servers.

You could join private trackers TurkTorrent or Broadcity. They upload DUAL versions of TV series and movies if available. I don't know if they will open registrations but you can ~~get~~ buy an invite from their homepage. (not recommended)
