I use "location specific" PVA's and IP solutions and order all of them prior to starting your campaign. I prevent ghosting because of the methods I use and because of my years of experience with Craigslist and all of their updates. I work for one of the largest U.S based Craigslist Posting services that has great reputation and reliable posters. We can handle up to 1500 ads per day, and manage hundreds of clients monthly. I would be happy to talk business with you, PM me and we can talk in private.
