Noahs Classifieds

Any one here used noahs classifieds to make money?

i put a free version on a site of mine years ago and now all of a sudden its getting people registering, i think most of them are just link building but there are one or 2 selling things.

Surely someone must have Noahs classifieds on a site? Is there anyone making money with them?
If you are what strategy did you use to get the cash flowing?
