It is just not worth to buy gold. For example, we learned the hard way when our Wow account got permanently banned because we engaged in buying gold from one of these sources. We had had that account for some time and had multitudes of the best weapons, armor and items. As we continued to try to be the best we had to have gold to get some of the latest items that would come out, we got caught in this horrible downward spiral of addiction and didn't think twice about buying gold. So we lose a World of Warcraft account. Buying World of Warcraft gold is just not a smart move to make considering the investment of time and effort you put in to even get to the point where you would need to buy gold. World of Warcraft is also be very expensive. The in-game currency is gold, silver and copper. One gold piece is 100 silver pieces and one silver piece is 100 copper pieces. There is a black market of sorts that is based around selling massive amounts of this gold currency used in this game to players all around the globe. The players refer to these people as gold farmers.
The wow gold farmers usually work in literal sweatshops filled with computers with Wow installed on them, and rotate in 24-hour shifts to farm gold so that they can sell it over the Internet. The leaders of these online gold farming sweatshop rings are usually business men of some standard, hiring people that will work for a dime who are so addicted to the game to work tediously to farm gold which players then purchase and receive through in-game transactions.
But why do Wow players buy this gold? This is because that they have too, the game is very overpriced, especially on older servers, that most players have no choice but to buy wow gold from these online sweat shops. How you do in the game is about 95% based on the items and armor on your character. That is, there is a huge demand for the great items in the game, and if you've taken any basic economics you know that if demand is high, firms or in this case the players selling the gear, can charge ridiculous amounts of gold. So instead of spending hours and hours farming gold for them, the players simply log onto one of numerous websites that sell wow gold and buy much they need, and in 30 minutes to 2 hours they have received it and most don't think twice about it.
There are several risks involved when buying from these online gold suppliers. In the World of Warcraft, an account is a huge investment, and if you buy gold you are adding an obscene amount of risk to that investment. Your credit card information that you use to buy the warcraft gold is also put into the hands of someone across the world that is basically engaging in illegal activity. There is also risk for identity theft and things of that nature when handing out your personal information to the non-trusted websites.
