Hackers starting on Horntail?

That's assuming the hackers are even taking buyers and not just doing it for the loots that they can they release in a trickle to keep the prices maxed, because if they take pendant and egg buyers that means witnesses. Not that they're very bright or subtle, but would you pay a group mesos to do something to/with your character that could result in all your hard work being banned permanently?

Exactly. Besides, saying the GMs aren't doing anything is pretty stupid in my eyes. Even if they AFK for half an hour or so, there's no way they can miss a few blue notices in their chat box.
