As Eyonix stated in the US World of Warcraft Forums. Blizzard enforces harsh politics versus cheater, goldfarmer and user of 3rd party software. 59.000 Accounts with a total of 22.000.000 Gold have been banned this June.
As part of our efforts to eliminate cheating from World of Warcraft, we recently banned approximately 59,000 World of Warcraft accounts in the month of June, and with that removed well over 22 million gold from the total economy across all realms. While we regret having to take such extreme action, these accounts were participating in activities that directly violated World of Warcraft’s Terms of Use, including the use of third-party programs to farm gold and items. Such behavior not only negatively impacts the economy of a realm, it diminishes the achievements of those who play legitimately. We will continue to aggressively monitor all World of Warcraft realms in order to protect the service and our players from the harmful effects of cheating.
I merely wonder why the European World of Warcraft Team is not as rigorous. They have more players, but ban much less Accounts.
