Do not forget about the "Farm" games that are doing the rounds. You are asked to breed with some kind of virtual farm
animal {These scammers change the type of farming animal with every new site} and then you buy feed and better animals
with your own money. The profits is supposed to come from the off-spring of these animals or the eggs or milk that these
animals produce. The problem is, they are buying the produce from the virtual farmers with the money that people spend on
the virtual add-ons and when this runs out and they made enough money, they simply close the site. Later a new version
of this will pop up with some other type of animal.
