The bloke, who is a network network engineer for an ISP, reports his experiences with the Blizzard administrators here. He thinks that the use of Wine might affect the software Blizzard use to detect third party programs designed to cheat the game.
However, just in case, he said sorry to Blizzard because he also used a programmable keyboard. He pointed out that the Terms of Service do not say anything that such keyboards are not allowed and Logitech has even been advertising them as useful for WoW players.
None of this seemed to impress Blizzard who banned him anyway, without really saying why and any emails he send them seem to be getting an automatic reply.
The bloke is a bit miffed as he has played WoW for about a year and have a 60th level Mage who will die if he doesn't get enough attention. µ
