I dont believe this is a money making move by blizz, and god knows how I hate the vanity shit they pedal like a crack dealer on a corner. However, they will still make money off of the change.

Hackers will always adapt and prevail no matter the security measures of blizzard. Time is money, even in a virtual world. Furthermore, hacking accounts is a no risk venture, its no wonder its a booming business.

Blizzard alone sets the price of gold and accounts. I am sure anyone who has bought and sold accounts or gold knows of what I speak.

Blizzard could stop the hacking so easily by not placing artificial prices on gold/items or accounts(achievements). Again time is money, even in a virtual world.
