Demonoid
BitMeTv was my first private tracker. Happened to find it while searching for an episode of something and they were doing open signups at the time. It was great for several years before server crash and they couldn’t get it back up.
The original Cheggit, before it became re-imagined.
Most of the regulars then jumped over to EMP who were very welcuming.
U2 dmhy is my first private torrent, I got it from my friend 2 years ago and it is the only private torrent I have until now.
my First Private Torrent Tracker is HDWing
My first tracker was MyAnonamouse
My first was TorrentBits, founded in 2004. Closed a year later, and from the ashes rose TorrentBytes. Sadly that one is dying as well now.
First was Pleasuredome, but you didn't need an invite for that, so then first invited was TorrentDay
PrivateHD. I would love to get a foot into either TorrentLeech or BeyondHD.
