If you right click a torrent and select remove, it automatically deletes the torrent files that qBT stores in the appData or home folder. If you check ‘permanently delete files’ it also deletes the media associated with the torrent file.
Most people dislike uTorrent because of the fact it was loaded with malware(cryptominer) and ads(hopefully the version you are using is before this crap). Also, download speeds are faster on qBitTorrent.
That being said, the UI is definitely a little different and I understand not wanting to learn a new workflow. You do what works best for you, friend.
You bring up a good point. What qualifies as a mask? Do fake beards and mustaches count? What about religious face coverings? What about people who have prosthetic noses? I have a feeling this is going to be a tricky one for them to enforce in any sort of reasonable way.
