Eventually, particularly when trying to download old torrents, most BitTorrent users find themselves with a transfer which stops due to the swarm having no seeds, not enough peers to cover the full release, or the tracker going down. btReAnnouncer is a handy site which could prove vital in reaching that magic 100%.
It helped me, looking for a torrent of an ebook that had no seeders.
It's very helpful actually. Consider the average torrent forum member who posts once or twice, some material that is both rare and not in demand. So he posts on a couple of forums, and sees no interest or very little, then decides to stop seeding.
This basically helps you reconstruct the torrent if some of the leechers have different bits from the different trackers, adding up to the full 100%.
Or at least, that's my assumption. It did pull together something for me I'd been trying to get for three months now, so reps to the TS.
