Blizzard have made a new posting on the European World of Warcraft site, discouraging players from buying gold and power-leveling services outside the game. Blizzard explains the the negative effects of such services.
"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."
