Also asked them if torrenting legal stuff is allowed and they said no.
If you are on VPN they cannot know shit. Only that you use a VPN… So either they are detecting the VPN and lying about what they know or you fucked up setting the VPN and the torrentina doesn’t go through the VPN.
They’ll still see upload/download volumes, speeds and patterns. Just not destinations. That alone could indicate torrent.
That could indicate a lot of things. It would be very difficult to distinguish a torrent from something like cloud folder sync. And that would still be a statistical guess. No ISP is going to go after customers because their VPN traffic is potentially torrent traffic.
Besides, even if they could detect that torrenting is taking place, they will not know what data is being transferred from and to where. It’s a meme, but torrents are actually sometimes used for non-copyright infringing data.
I was providing Linux distros and Machine Learning datasets some time ago, because official servers where slow. I’m the meme I guess
