Legal Question in Civil Litigation in Oregon

Re: Public Internet Forum / Professional Libel or Slander

You can sue the person for libel.

While a person who makes a formal complaint to a government agency has a privilege that negates libel, merely posting claims about your behavior on a web site does not have that privilege. Further, any outright statement that you have broken the law or engaged in illegal conduct is a very potent version of libel. Since you are not a "public figure," you need not prove that the person posted the claims about you did so with "malice."

Of course, suing for libel will probably cost you money, although some plaintiffs' attorneys might take the case on a contingency basis (get a share of any judgment but not otherwise charge you for their services).

You would need to prove, however, how the libelous statement harmed you in a concrete way. Did it prevent you from keeping or obtaining employment? Did it nullify your opportunity for consulting work? Did it make you an object of ridicule at work? That sort of thing.
