It is my understanding that ISPs block IP addresses and domains under court order now for copyright violations, criminal activity which would include CP. They require a court order as they cannot ascertain if it is CP or not, that is a Law Enforcement decision. The US Supreme Court decision's was just being nude is not lewd, also with aging software which can regress photos, LEOs in the US have to ascertain if this is CP or photo shopped.
