As long as it’s in your list, your client keeps a copy of the torrent file around somewhere.

(FYI: either something piques your interest, or your interest peaks at some point)

I took it as a chance to weed them out. I went through each one manually and made a choice whether to keep it. Went from ~260 to 130.

I also unsubbed from each so as to make yt unusable, so I wouldn’t be tempted to go there, unless specifically looking for something.
