I advertise my business on craigslist.com There is an option when submitting the ad that I always leave on which says it’s not ok to contact this advertiser with other businesses. And yet everyday that I post an add I get 4 or 5 people doing "reverse marketing". This means they contact me as a potential customer, sometimes just trying to sell me outright. This is exactly what I specifically said I didn’t want anyone to do. So I’d like to use their email addresses and sign them up to some sort of spam network so that their email address gets inundated with spam. Where do I go to do this?
