That goes to buyers as well. No feedback after they get something. PM is the only way to go. Spam and fake emails sent for something listed has been going on for a while. No way do I post my personal contact info in an ad. Being cordial is the only way to go. If someone offers a low ball price, I just reply with a simple no I pass. Of course some people take a low offer as an insult, get over it and move on is how I handle it. I see it as rude when people come on any site and whine that they couldn't get their price so scrapped it for less money.
