Because the auction site will possess sensitive data, including your address and possibly a credit card number, you need to be comfortable with its privacy policies before you disclose your personal information. All services have public user-feedback systems that allow users to grade other members and their transactions. Information about how you conduct business is never considered proprietary, and will not be protected by a privacy policy. Be Familiar With Selling and Bidding Policies Familiarize yourself completely with how the auction site expects business to be conducted before you go through the task of completing your registration. Typically, auction sites won't guarantee the legitimacy of the items being sold or the conduct of buyers and sellers using the site.
Users are responsible for judging the reliability of other members and their merchandise.
If, for example, you fail to deliver goods after payment is received, you could, at the least, receive negative feedback about your listings, discouraging future buyers from purchasing your goods. At the worst, you will be charged and prosecuted for various types of fraud. Online auctions will often arbitrate disputes between buyers and sellers. Finally, all auctions reserve the right to cancel your membership if you violate their terms. Before you begin, you must first confirm that you're at least 18 years old.
