No. We only allow private trackers. (Trackers that require login to access torrent files)
We no longer authorise the use of public tracker on our network. Not only are they a security risk but they take up a lot of bandwidth and only used by a minority of seedbox users. For these reasons we now actively block and limit public announce/non-authentication based trackers.
Public trackers are for n00bs anyway. You don't need them!
