Netflix reported substantial growth in subscribers in the months following its push to stop users from sharing accounts with people outside of their household.
Yep, and pretty powerful for sharing too, as you can simply link an entire movie or series episode via hyperlink.
Generally, but the way movie-web and goku.sx work is that they’re linking you to cached streams pulled from torrents and hosted on separate servers like Upcloud - you’re only viewing the content, not hosting it. As such your risk of being prosecuted is considerably less than directly torrenting, especially if you’ve got decent privacy protections on your browser.
That being said, safety first unless you trust your ISP.
