Have you tried contacting Craigslist?
If you go to Craigslist, on the left hand side there is a place to click and it says, "help, faq, abuse, legal"...I would click on that link and then scroll down to the bottom where you can go into their help desk discussion forum or send them a note.
Good luck and keep us posted...it will be interesting to see what craigslist has to say!!
