No, you hire GMs to track and ban bots and gold buyers. But Blizz won’t do that.
And some things (like GDKPs)…’encourage’ gold buying a lot more than others. In a completely unpoliced game like Classic that’s a problem. You might not buy gold, but many players do.
Like I said, I’ve seen this start to creep into Classic Era. Boosts too (which are largely paid for by gold buyers). If Blizz isn’t going to deal with the bots and the gold selling business, I don’t ask for things like gdkp and selling boosts to be banned. I just quit. That’s not the game for me.
