You also get access to a broad repository of the history of a particular torrent. Like ever preferred a really obscure version of your favorite torrent? Probably impossible to find unless it was a really popular Vidya game and there's a legacy torrent still seeding.

I've still got a Myanonamouse (Private Book Tracker) account purely because there are certain editions of books that quite literally don't exist in print except as a used copy on Amazon. But because some degenerate decided to commit all their scans to a Seedbox, ebook versions of obscure early science fiction now exist.

Very niche, but also incredibly useful if you come across something that you just can't find elsewhere.
