Quote: "emailed the person directly with some results/suggestions. No response."
I've had people selling on craigslist completely ignore my emails and the ad remains up until it expires. Leaves you hanging, wondering. Did the item sell and rather than reply saying it sold and deleting the ad, not response to people's emails. Or did they ignore everyone's emails and not even sell it? Who knows? Annoying as heck but it's not because they feel I'm a predator. Some people are just too damn lazy to respond even if it's something to their benefit for which you emailed them.
