I just read the User Agreement and Terms. There is not much guidance IMO on what would be considered permissible or not permissible posting. These two sections seem relevant:
User will not "Post false, inaccurate, misleading, defamatory, or libelous content;"
and:
"We may, in our sole discretion, limit, suspend, or terminate our services and user accounts, prohibit access to our site, services, applications, and tools, and content, delay or remove hosted content, and take technical and legal steps to keep users from using our sites, services, applications, or tools, if we think that they are creating problems or possible legal liabilities, infringing the intellectual property rights of third parties, or acting inconsistently with the letter or spirit of our policies (for example, and without limitation, manipulating Feedback, circumventing temporary or permanent suspensions or harassing users). We also reserve the right to cancel unconfirmed accounts or accounts that have been inactive for a period of months, or to modify or discontinue the Fredmiranda.com site, services, applications, or tools."
