Honestly not really that big a deal. So what if 20b zeny came into the server. Zeny sites probably can generate that much in a few weeks, with probably no one to sell it too. Could just pretend some luckbox got a GTB, sold it for zeny and disappeared. Not like you can buy any god items or MVPs with zeny on classic. IMO OP is just a whistleblower who's trying to destroy classic. Obviously the GMs need to fix it, but doesn't mean OP should cause panic amongst Classic players by posting this.
What the -_-?
