This is actually criminal in both Alaska and Oregon.
Revenge porn could fall under § 11.61.120 (harassment in the second degree): “(a) A person commits the crime of harassment in the second degree if, with intent to harass or annoy another person, that person— 6) publishes or distributes electronic or printed photographs, pictures, or films that show the genitals, anus, or female breast of the other person or show that person engaged in a sexual act.”
(1) A person commits the crime of unlawful dissemination of an intimate image if: (a) The person, with the intent to harass, humiliate or injure another person, knowingly causes to be disclosed through an Internet website an identifiable image of the other person whose intimate parts are visible or who is engaged in sexual conduct; (b) The person knows or reasonably should have known that the other person does not consent to the disclosure; (c) The other person is harassed, humiliated or injured by the disclosure; and (d) A reasonable person would be harassed, humiliated or injured by the disclosure.
So someone in your situation may wish to have an attorney (or yourself) write a letter to them, stating that if this is done, then a criminal complaint would be filed, and in addition, she would be sued for (a) negligence per se, (b) intentional infliction of emotional distress, and (3) invasion of privacy.
Let me know if you need an example of such a letter. It is best that an attorney sends this on one's behalf as this carries more of a threat than simply sending it one's self.
