Ot of curiosity, how does this work? If a site is over https, then the only information I would think the ISP would have is the subscriber downloaded from randompiratesite.xyz what seems to be a single X GiB file. They could see that the size roughly corresponds to FooBar.mp4 on that site (plus some HTTP headers). But this seems pretty unreliable. (Like what if someone was using a download manager to get multiple large files at once, using multiple download streams per file?)
I'm sure that you can get in plenty of trouble for downloading a ton of data from randompiratesite.xyz or whatever, but how the ISP determine the number of movies they've seen you download?
