File suit against her for slandering your name. Unfortunately I do not know how the courts work there but could probably help if you need to figure out how to phrase things to get the Court's attention.
Start keeping a journal of her antics. Keep details and have statements from those who know of her behavior on-hand in case she ever pulls some other shit and you actually get arrested.
I have everything recorded already. The police actually have 8 months worth of unsolicited messages. And copies of her acknowledging my telling her I wanted no further contact from her. But apparently that isn't harassment (because I'm a big guy and she's the poor defenless woman).

I'm going back up there in the morning, and to the court to get papers. What I'd like is for her to be charged with harassment and have an injunction issued.
Tonight's message included threats so maybe that'll spur their assess on.
My meltdown has passed, I'm rational and collected again. But Craigslist can be a backup if the legal system completely fails me.
