Craigslist Marketing find solution to automatic flagging issue

I run a computer shop in coraopolis PA called MDofPC Doctor of Computers [login to view URL] and about 2 months ago all of our craigslist adds are getting flagged no matter what we do within hours. We have tried a variety of methods including automated software, proxies and different accounts. Open to suggestions and trying different things Will even provide remote access to our posting computer This project would only be considered complete when a solution was provided that resolved the flagging issue. Providing a way to keep at least 100 ads online. We used to be able to post our content without problems prior to a few months ago. Our ads go live but within 2 to 4 hours they are flagged.
