You are not absolved from using your own judgment in evaluating an offer. There will always be new scamsters arriving here - perhaps we can keep them from making our net their home. No actual employment existed. Ask yourself why, if you knew of a way to make thousands of dollars a month at home with a computer, you wouldn't just pay someone a salary of mere hundreds of dollars to do it for you. As everyone knows, lotteries are a method of selecting prize winners by random chance.
Great care is taken to assure that the selection process IS random and fair.
The government, state and federal agencies often use a lottery method to distribute limited resources fairly and impartially. This preserves some order in the broadcast system with TV neatly separated from radio and cellular phones. When it is deemed appropriate to release some of the unassigned radio frequencies for a new purpose, as was done recently for wireless networking, the government establishes a lottery to randomly award the frequencies to potential developers of the new system. Since the government, in it's wisdom, has decided not to issue green cards to all applicants, a lottery system was designed to fairly distribute the limited number of green cards among all of the applicants. Now the rules for entering the lottery are simple, clear, and available to anyone who asks.
