And voila, the underhanded Craigslister has eliminated anyone else from responding by pulling the ad, giving him or her the best chance of getting your deal. These pieces of software are most often used by people looking to make a profit be reselling cheap or free items.… So if you do frequent Craigslist, especially as someone who regularly gives products away in the free section, please monitor your post and don’t just give the product away to the first person who responds. It could be that Auto Flagging Software was involved and someone who genuinely needed the product was shut out be someone else just looking to make a quick profit from your generosity.
