In the US rule about copyrights mainly through the Digital Millennium Copyright Act (DMCA) focuses a lot on giving out things with copyrights While putting stolen things online or letting others get them is wrong just watching them without saving a copy is harder to judge legally

Internet companies often send notices when they see action on sites known for not having permission While people who just watch are not often taken to court those who keep doing it might have their service stopped

The European Union is stricter after a 2017 decision by the European Court of Justice (CJEU) This says clearly that watching things with copyrights from a place without permission is breaking copyright rules This is true even if the user does not save a copy

How strictly this is enforced changes between EU countries Some try harder to catch users The main thing is if the user "knew" the site was illegal
