·Be aware that an organization without complaints is not a guarantee. Fraudulent operators set up shop and close down quickly, so fact that nobody has made a complaint doesn't mean seller or charity is legitimate. You still need to look for other danger signs of fraud. ·Understand offer. A legitimate seller will give you all details about products or services, total price, refund and cancellation policies, terms of any warranty, and delivery time. ·Think twice before entering contests operated by unfamiliar companies. Fraudulent marketers sometimes use contest entry forms to identify potential victims. ·Be cautious about unsolicited emails. They are often fraudulent. Recent legislation requires all marketing emails to include a working link that enables recipient to be excluded from future mailings. ·Beware of imposters. Someone might send you an email pretending to be connected with a business or charity. Others may create a website that looks just like that of a well-known company or charitable organization. If you're not sure that you're dealing with real thing, find another way to contact legitimate business or charity. ·Beware of "dangerous downloads." In downloading programs to see pictures, hear music, play games, etc., you could download a virus that wipes out your computer files or connects your modem to a foreign telephone number, resulting in expensive phone charges. Only download programs from websites you know and trust. Read all user agreements carefully.
