I just read a Post about this and i can very much see where blizzard is coming from on some of this however i disagree with part of a statement that was made about botters using other accounts.
While Yes I agree that Gold Farmers and those Selling gold hack accounts to use others in order to get money, I have recently found out that Bot programs can be bought online and more and more people are buying them to bot for themselves to get rich. This is drastically killing the economy of some servers, these people claim they have their girlfriends/ younger siblings doing the farming for them and have "auto" responses for when you try to message them i found one a few weeks back where i just kept psting them over and over and the messages i got back began to repeat themselves it was utterly disgusting in my mind that it would get to a point people would be so greedy as to buy a bot program for wow like those of Diablo 2 in order to farm and kill the ecomony.
As its stated in the other post by Nevalistis Blizzard is working on things to be done about this and Nevalistis states "It's more effective for us to study what they're doing so we can break the process at a larger level" This to me sound more like blizzard is focus'd more on gold farmers selling gold and hacking accounts to bot than the increasing problem with individual people buying bot programs to just get fairly rich for themselves. (The Link posted by Nevalistis was to an article on power lvling and gold buying).
So i guess what i would like to know is what is in the works to stop this? because in reality i see people with their own botting programs even if its not profiting them as a larger problem for us as players than the websites selling gold. in the last year I have met atleast 12 people on my low pop server of Drak'Tharon alone that use these Boting programs and not selling the gold but just becoming rich for themselves, and i'm sure their are many more. If this is a problem on a low pop server i can only imagion how bad the economy is dropping on a high pop server.
