Your TGx link is broken, I found the correct one at https://torrentgalaxy.to/forums.php?action=viewtopic&topicid=2657 EDIT: Nevermind looks like Lemmy itself keeps breaking the link, try this linked version instead
Sort of related question: Do any of the torrent indexers with DHT crawler currently index Bittorrent V2 hashes? That would seem like the easiest workaround for finding V2 torrents since none of the general public/private sites have V2 support.
(I'm talking about sites like BT4G, BTDig, SolidTorrents, BitSearch, BTMET, Libtor, etc.)
