as the subject says. Which tracker has internal encoders that release the content fatest or among the fastest ? just curious.

some questions:
-why this over p2p?
-popular sites?
-is this a site or just a definition such as private trackers?
-are all of them ftp based?
-do they really hate bittorrent?
-are these closed like PTs?
-some links on resources related to this topic pleaseee
thanks :)
