MazeTorrents is a fairly new private tracker which tracks a decent amount of general/0day content. It is evident from site messages and some releases that MZT is of Romanian origin. However the interface and most of the content it tracks is in English. Apart from usual uploads, they do have a requests section where users can request releases currently not on the tracker.
MZT currently tracks a little over 500 torrents. Apart from the usual scene and non scene torrents, it also tracks some large packs.
