Craigslist postings?

[vitalpro]

Hey all, I am trying to post ads on craigslist but I'm sure that you all know that it can be a tricky process. I have about less than a 5% success rate with my ads. I see people on there flooding the shit out sections with the same type of ad barely even changing anything. Not only that but they are spamming the same ad in different sections of craigslist. my question is how are they doing this what is there method? Do you guys know of any ways to spam that same way. My content is not related to theirs so i'm not really hating on them, just want to know the work around of craigslist's terrible system.
