The European Union considers it illegal to force some websites to accept cookies to display content to their visitors.
Actually, forcing visitors to accept cookies is an application that is blocked by law in Europe. However, it is common for websites to wrap around this law in different ways and still force their visitors to accept cookies.
European countries will now publish an expanded regulation to make the law more enforceable. It seems that there will be heavy penalties for websites that force their users to accept cookies from now on.
