Blizzard continues to uphold its aggressive policy on exploits.

Blizzard Entertainment has permanently banned more than one thousand users from its massively multiplayer World of Warcraft title after an investigation into "Hero Online Gold farming".

"If you suspect someone of taking part in said gold farming, please email the report to here, he added.

Since the game launched in the US last November, Blizzard has been firm in its apparent zero tolerance policy on cheaters, suspending a large number of accounts for a variety of reasons and encouraging users to report anybody suspected of hacking or cheating the game in various ways.

An investigation into gold farming, which involves collecting large amounts of gold and selling it to other individuals in exchange for real world currency, has been going on for several weeks.

In a posting on the game's official forum, in-game support manager Maleki said Blizzard has "issued permanent suspensions to over one thousand accounts that have been engaging in this practice".

WAR fans can then take this code to the Mythic Account Center and enter it into their account. Once activated, players will receive a unique Scarab Amulet reward. This fun item summons a Scarab swarm that chitters and swirls around a player's character.
