Blizzard's Warning: Gold Buying Must Stop!

when I saw this title from official site, I was just wondering that Blizzard was starting supporting Gold Buying? But the notice proves all things are going well, it's just my false alarm.

Gold Trading becomes so much more popular than ever before that shocks Blizzard. More and more gold famers and gold trading service companies' appearance shake the economy system in games. And more and more requirements become the rocket propellant of gold buying.

Now Blizzard announced a warning in the official site of World of Warcraft.

• Gold Trading is the large impact it has on the game economy.
  
• Many accounts that have been shared with power-leveling services are then hacked into months later, and all of the items on the account are stripped and sold off. That becomes a originate of Gold Buying.
  
• Most of Gold Selling Companies are Gold Stealing Companies at the same time. That means the gold that you just bought from a company might come from other players' accumulation. And that might be the way you have one day.
  
• And more...

We would like to make a clear statement here about the negative impact of buying gold and using power-leveling services. Every day, we encounter players who have been negatively affected and targeted by companies offering these services. So, we hope to raise awareness about the practices they engage in and the detrimental effects they have on all players, including their own customers, as well as on the game environment as a whole.
