My husband can't post ads on craigslist they keep getting flag help!!!!!!!?

My husband makes a living selling things on craigslist. For the past 3 months his ads get flagged and removed as quickly as we post them. We have tried everything: bought an auto ip address changer, change the account daily to new e-mail addresses. We have changed the words in the ad even went as far as to take the stuff to a different location to take pictures. We are losing a ton of money every day that pes and we even went to Craigslist headquarters in SF and they told us they offer no technical help for its users. I am desperate!!!! Please help. I would pay someone to help us at this point.
