Currently, EU Publishers Can't Block US Users Without Blocking Google

There is currently no safe mechanism for European publishers, or any publishers outside of the US, to block US based users and also not block Googlebot or Google from your site. Google crawls from the US and if you block US users, you would also have to block Googlebot to not implement cloaking which is against Google's webmaster guidelines.
