The bots create literally millions of gold that wasn’t in the economy. The gold buyers buy that gold, they use that gold to buy stuff in GDKPs for stupid amounts. That gold gets spread to non-gold buyers. They buy out the auction house. They repost for higher pricers. Other gdkpers no longer care about the price of items. They pay whatever they have to. People keep posting for high prices because it sells. Everyone has to find someway to afford their consumes so they also do GDKPs.
This is reality. This is what happened. I know it doesn’t suit your narrative, but that’s how this works.
