D.H.
C.,
I am so sorry that this happened to you. I am a massage therapist and it disgusts me that someone would use our profession to hurt others. The first thing you do is report this to the police department of the city where this happened. You didn't go into detail about exactly what was inappropriate, but any unwanted physical advance should be reported.
Second, report this to Craigslist. They will assist the police in finding the people, (At least the email address and information they used to post the ad.)
Third, there are massage associations that could sanction the person if he is, an actual therapist. The biggest ones are the IMA, International Massage Association, and the ABMP the Association of Bodywork and Massage Professionals. You can find them online.
Please feel free to email me if you think I can help in any way or need to talk to someone further about this.
