Craigslist's bad move

been struggling to get that code that they were saying. have entered our Colorado number for five times already but got no call from them. have also used four Colorado phone numbers already but all of them cannot be verified according to craigslist. is it because we are using a VOIP? but they must have provided us with a valid reason and not that same repeating error message.
yeah, craigslist (CL) is basically data mining so they can sell info to 3rd party taggers. two of the sites that we're working on are mainly depending on CL and now that they are very strict on the postings that we're making, obviously business is not quite working well for the moment and it's kinda hard 'cause there are no other sites that can be compared to it. Kijiji.com and Backpage.com are not that effective, you will experience a lot of errors even while you're still in the process of posting your ad. It's kinda frustrating! We swear if ever CL will continue and live to that verification procedure and always not attend to our problems, we'll totally leave them and go to another site like many other online marketers are doing for sure.
They better fix what they screwed up or they wont have any business left.
