Advertisements for goods on sale or auction sites are often cloned after the original sale is complete. Details of the merchandise, photos and seller details are faked and offers to purchase are invited from other users of the site. When a person tries to purchase the goods from the ‘seller’ they are asked to complete the sale using a money transfer service instead of a secure payment service such as PayPal. Always use a secure payment service where refunds are guaranteed in the event of fraud and only purchase from reputable sellers. If unsure, walk away.
