Obviously Blizz should just ban GDKPs. They’re horrible for the game and for the community. They’re directly linked to gold buying. They’re the main reason you see so many bots.
But Blizz will never ban them. They want the whales. They want the bots. A sub is a sub, and the majority of Classic players love being gold and buying gear with that gold. Also, Blizz would actually have to hire GMs to police the game. Why do that when they can just ignore the problem?
