When I started this thread, I thought that the phrase "I seed 24/7" was a generic tag used by many people. After doing some searching, it would seem to be one user (or bot), as the torrent descriptions all start with "I seed 24/7 MEDIAINFO:"
I'm still not sure what the value of that phrase is: It might have true when the torrent was uploaded, but there are lots of torrents on the system with this tag that are dead (meaning nobody is seeding them)–some as recent as a week ago. Of course, saying something in a torrent narrative isn't a permanently binding commitment; at the very least it means that the user is continuously seeding the torrent after uploading it, which is required by rules anyway. If, though, the user is seeding hundreds of torrents along with the new one, it's going to be a slow process (as MrMazda notes above).
