I been lurking the site and they give bad info to those who say they been falsely accused of fraud. They said they cannot sue. As a matter of fact, those who are accused of fraud can sue for libel per se.
Libel per se
N. Broadcast or written publication of a false statement about another which accuses him/her of a crime, immoral acts, inability to perform his/her profession, having a loathsome disease (like syphilis) or dishonesty in business. Such claims are considered so obviously harmful that malice need not be proved to obtain a judgment for "general damages," and not just specific losses. Https :// dictionary. Law. Com/Default. Aspx?
