Has anyone had trouble with their posts not getting posted?

I post ads a lot on craigs list for Hits 4 Pay, My Power Mall, my real estate services and/or real estate listings and if I go to my account it shows that they have been posted (sometimes Hits 4 Pay posts are flagged because it's against the guidelines) but then it'll show up as flagged but for my active posts - when I do a search to see my ad live it's never on the website. I know through the craigs list forum a few people are complaining about this problem. Have you had this problem? Is there a way to rectify it? It's a lot of wasted time creating the post and not having it on the site.
