It's a problem many game companies/ environments deal with, MMOs with game economies and "duped" or spoofed items or currency. Blizzard might ban hundreds of bad accounts in a wave, potentially having a big impact on game economics. It takes them a while each round... But it's sort of a question of wait until there are enough exploiters or enough complainers before having to address and correct it.
Is it better to say open new T11 accounts and join the fun, or spend that time on social streams talking about how this exploit effects your gameplay experience, and encouraging people to speak up..
