yeah, ive had a few e-mails like that (I do have a WoW account) and my ex's mam got some too (who doesnt have a WoW account).
i did raise it in several WoW forums but i dont think i ever got anything back, although i was posting around the time they were having massive problems with moving to battle.net. during that i some how lost my account.
was so funny, there was a huge bug where you were able to register any account you wanted by typing in the account name, this kid got like 10 accounts on one account and Blizzard were so snowed under with technical support request it took them weeks to sort it all. ahh fun times.
LOL it isn't as bad as a game a used to play called Knight Online World. The way their staff worked was unbelievable. I don't see how anyone could even see how this would work. Well the biggest problem in this game is that bot programs are an easy reach away, you can google search it and it would be the first link. So everyone would bot, you would know someone from 75 and lower who botted. It would essentially be an easy fix, just keep the developers of the bots at bay with patches to fix that problem.
It wouldn't work with this company because they were only the publishers, they could not modify, add or remove anything from the game until the developers in Japan sent them what to add. So you can imagine how later the thing would come in. Well it takes them about 2 months. By that time the developers of the bots would have upgraded their bot program to work better. Eventually having arrows to shoot out of a bow did not matter, you could buff yourself with a click of a button, you could heal your whole party while being AFK, you can even hit 5x what you should normally hit.
So when the patch rolled in, this is what happened. A window would pop up, "You have been disconnected for using 3rd Party Tools", all you would need to do is log back in. Eventually the delevopers would find a way to get rid of this and go on about their business for another two months, developing auto loot, auto party add, auto party delete (if character is idle), auto party add (w/ whisper password). Can you imagine this.
It is simply unbelievable how someone could run an MMORPG that is a harbor for aspiring unethical hackers (crackers). Sad.
By the way I botted two accounts to level 77 without getting banned. The cap in that game for level is 83... Accounts still not banned, but are just sitting there when they start to get their things in order.
