It appears that customers who dutifully followed ArenaNet's suggestion to "create dedicated email accounts for GW2" are receiving those "password reset" emails. If this is the case, that pretty much blows apart their theory that accounts are "being hacked into as a result of farmed accounts from OTHER games". It seems to me that ArenaNet is trying to avoid responsibility for their own third rate security/authentication system. In response, this guy hits the nail on the head:
"Has it occurred to anyone that there is a possibility the support website (http://en.support.guildwars2.com/) has been hacked?
Support ticket CMS has a notoriety for this kind of thing.. I'd be careful. DO NOT use your game email / password when registering on their support website!"
