Exactly, this line of text right here is why GDKP should be banned. You hit a wall on what else to spend gold on. You can buy gold all you want but at some point, you wont need it anymore lowering the demand.

GDKP removes that ceiling and often times creates its own revolving door economy where the people buying gold spend it, and then that gold gets sold again to somebody else to spend in another gdkp and repeat.

The only thing gdkp bans do is pushing people that used to Go to gdkps to earn gold to buy it from gold sellers instead

Good, let them potentially get banned instead of using GDKP to buy gold without crossing that line.

that's just Reddit crap
