Intellectual property laws are generally more internationally recognized by various treaties than any sort of criminal law. That said, the only ways content can really be removed are to either ask the site to do so voluntarily, or get the government to force their hand.
The former rarely works and the latter… well, it really depends on who you are dealing with. Some governments are cooperative, some are apathetic, some have power and skill, some are powerless against this sort of thing, some sites are easy to take down, others are ingenious at finding ways to survive in the shadows.
Suffice it to say, those sites with resources and ingenuity cannot be stopped. Not allowing them to function will to prevent them from functioning; they will just keep on keeping on no matter how strenuously they are disallowed. Sometimes “allowed” only means “unable to be prevented”.
