" a foreign Internet site or portion thereof is a `foreign infringing site' if--
(1) the Internet site or portion thereof is a U.S.-directed site and is used by users in the United States;
(2) the owner or operator of such Internet site is committing or facilitating the commission of criminal violations punishable under section 2318, 2319, 2319A, 2319B, or 2320, or chapter 90, of title 18, United States Code; and
(3) the Internet site would, by reason of acts described in paragraph (1), be subject to seizure in the United States in an action brought by the Attorney General if such site were a domestic Internet site."
Which then follows up with:
(2) IN REM- If through due diligence the Attorney General is unable to find a person described in subparagraph (A) or (B) of paragraph (1), or no such person found has an address within a judicial district of the United States, the Attorney General may commence an in rem action against a foreign infringing site or the foreign domain name used by such site.
It also covers:
DEDICATED TO THEFT OF U.S. PROPERTY- An `Internet site is dedicated to theft of U.S. property' if--
(A) it is an Internet site, or a portion thereof, that is a U.S.-directed site and is used by users within the United States; and
(B) either--
(i) the U.S.-directed site is primarily designed or operated for the purpose of, has only limited purpose or use other than, or is marketed by its operator or another acting in concert with that operator for use in, offering goods or services in a manner that engages in, enables, or facilitates--
(I) a violation of section 501 of title 17, United States Code;
(II) a violation of section 1201 of title 17, United States Code; or
(III) the sale, distribution, or promotion of goods, services, or materials bearing a counterfeit mark, as that term is defined in section 34(d) of the Lanham Act or section 2320 of title 18, United States Code; or
(ii) the operator of the U.S.-directed site--
(I) is taking, or has taken, deliberate actions to avoid confirming a high probability of the use of the U.S.-directed site to carry out acts that constitute a violation of section 501 or 1201 of title 17, United States Code; or
(II) operates the U.S.-directed site with the object of promoting, or has promoted, its use to carry out acts that constitute a violation of section 501 or 1201 of title 17, United States Code, as shown by clear expression or other affirmative steps taken to foster infringement.
And they technically only cover 2 site types for support (ad companies, and payment processors).
Now, IANAL, but that to me says:
1) Site has to be dedicated to promoting piracy. (violating those above codes or counterfeit goods)
2) The operator has to be notified first
3) The operator has to ignore the initial request for action

So, a post on a forum would not ACTUALLY be enough to shut the site down, whereas The Pirate Bay would be eligible
