That are "primarily designed or operated" for pirating, and have "only limited purpose or use other than" pirating? What are some examples of such sites?
Note that S.103 that we're talking about deals with "U.S. directed sites", among which, presumably most sites with domains of .com or .org would fall, since registrant for those domains is under U.S. jurisdiction, giving U.S. "minimum contacts" sufficient to assert its authority over the site. That's my reading, anyway.
