Well - part of the deal of me writing the app for the guy was that I would use it too. So the numbers I am reporting were my personal profits off of it - and I had a much lower posting frequency as not to compete directly with the guy who hired me to write the app. He ended up abusing the system and changed the configuration to go like every 5 minutes which caused Craigslist to make various changes like removing the ability to add links in the postings, then they changed the captcha system (which was still easy to bypass) and then finally they moved to recaptcha (I believe). I don't know how much more the other guy ended up making but I know he was easily pulling in more than me.
