For general reference, they're using Blogspot for their website. Blogspot's TOS include this paragraph (under "content"):
Defamation/Libel. Users should not publish any content that is unlawful, defamatory, and fraudulent. Note that an allegation of defamatory expression, in and of itself, does not establish defamation. The truth or falsehood of a bit of expression is a key element in establishing defamation, and we are not in a position to make that sort of fact-based judgment. That said, if we have reason to believe that a particular statement is defamatory (a court order, for example), we will remove that statement.
