I’m sorry but there is. Ban the bots, no more gold to buy.
And don’t tell me a company that has partnered with Google Deep Mind and IBM Watson AI projects can’t detect the DK named “Gzkbdke” or “Rekbcsla” with 4 other similarly named DKs in Blackrock Spire every day 24/7 is actually a bot.
Blizzard looks the other way on bots because they are a steady and reliable income source of their own. But they also generate a high Return On Investment (ROI), since the bots also keep the humans paying their subs too, so they can buy with lots of gold to spend in lots of GDKP pay-to-win runs.
