The World of Warcraft phenomenon might be affecting people in a more subtle way than we think. Yes, there have been some cases of dearth (allegedly) caused by over-exposure to WoW, but what's even more disturbing is that people are beginning to spend important amounts of money for this game.

As you know, the World of Warcraft is virtual world in which various characters interact each other, everyone representing a player. In order to buy items, services and various goods the player needs virtual WoW gold, the currency of the WoW world.

Actually, the main source to earn WoW gold is undertaking quests and interacting with the other characters (human and non human). Anyway, on the Internet there are many sellers of WoW gold, willing to give a player the desired amount in exchange of real money.
Real WoW addicts love those kind of transactions, because they want to improve their character, equipping it with new weapons, buying skills and more.
