RevTT is considered as an "Elite" private tracker in the Bittorrent community. The site gets 0day scene releases pretty quickly and is considered extremely hard to get into.
About private trackers:
Private torrent trackers are smaller communities which cater a limited number of users. In contrast to large public trackers such as "The Pirate Bay" and "TorrentBox", private trackers provide faster download speeds and less number of fake torrents. However joining a private tracker often requires invitation from an existing member. If you do not have an invite, you can join through normal registration when the private tracker 'opens' its registration.
