One thing I REALLY hope doesn't make it into the clone... Rarbg made a point of claiming every single entry was seeded, despite the fact that pretty much anything more than a few months old was in fact not seeded and could only be obtained if another user came back. If you wanted to grab a TV show that had ended a couple years ago, you could bet that many episodes had a number of peers listed who were hoping it would be seeded again, but they never were. I guess I should clear out that stuff from my client now, but I actually have entries that have been waiting for up to two years because I couldn't find them anywhere else.
So if any of the devs are reading this thread, please don't insult your users in this way. Rarbg eventually became my last resort for finding downloads since I knew I couldn't trust if anything was seeded, despite the high quality of the files that were represented when you could get them.
I've been getting pretty decent results from torrent magnet for awhile now. Really they just seem to collect listings from other servers, but their status of each torrent has been pretty decent.
