I'm familiar with CraigsList, but I'm not sure what it would take to successfully flag postings.
If you know how to do this or currently get paid for CL postings this may be of interest, I've never paid for services like this but I know I can afford 0.10 ten cents per posting that is successfully removed.
It ranges from 1-3 to maybe 10-15 daily (mon-fri). And over the weekened might be slower.
I would transfer total amount weekly through GAF.
I need to know what method you'd use, what is your time zone, and how long would it take to remove the postings once listings are submitted, and how often are you in contact with your e-mail?
Maybe we can even get a schedule set up for listings to be removed twice daily.
