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?
thepiratebay.org is one obvious example. Although this would seem to be a foreign site, it is actually a "domestic internet site" and a "U.S. directed site" under the terms of SOPA. This is because the '.org' domain (along with '.com' and some others) is a domestic top level domain under the terms of the SOPA. See Section 101. Definitions in the bill:

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.
I don't know of any that conform to what you said. There are plenty that fall under the scope of the wording of the law, however. The second use of the word "pirating" is you interpretation. I have no guarantee that others will make that same interpretation.
