Many times that’s true, too. One of the saddest things in torrents is seeing two torrents with identical contents that were created separately, or one just recreated so someone can add their website to it or something, thereby dividing the pool of possible peers.

I think one of the most interesting ideas in BitTorrent v2 is that hash trees are formed per-file, not per-torrent. So two torrents with identical contents could, if I understand this right, basically be considered one and the same. It would be cool to see more wide adoption and promotion of BT v2 https://blog.libtorrent.org/2020/09/bittorrent-v2/
