Don't let yourself become a victim of fraud. Only deal with people that you can meet in person, or feel you can trust mailing something to you. APOAds.com is not responsible for any arrangements or negotiations you make with a seller.
APOAds.com does not share your email address with anyone. In fact, it doesn't even appear on your ad (unless you write it into the ad itself). Potential buyers use a "Contact Seller" form to contact you. If you receive a random email from someone asking for some personal information, be cautious. It's safest to only deal with people you can meet in person. Read this article to learn what a phishing scheme is.
If you find someone is using APO Ads to spam you, let me know.
