@archiver55 To answer your topic question--no, there isn't a list of removed torrents that's available to users, according to what a moderator told me a few years ago.
As @john32123666 says, torrents can disappear if the copyright owner asks it to be taken down. Material from EnglishLads and OnlyFans is often removed. If the torrent is taken down but you're still connected to seeders and/or leechers, those connections will stay active and you can download/upload material from those other people. It will not, though, be counted by the tracker and figured into your ratio.
I can imagine its frustrating to have a torrent disappear when you're using it to boost your ratio. I suggest no using EnglishLads or OnlyFans for this purpose. The torrent you mentioned (Guys of London) sounds like it might have been a thinly masked bit from EnglishLads or its affiliated studios...and those folks watch this stuff carefully.
