Greetings again, Reika!
Thank you for your patience with waiting for a response to the investigation. After thoroughly investigating the matter, the development team did find this to be a potential problem with the game, and the matter is being worked on at this time. I recommend keeping an eye on both the forums and http://lodestone.finalfantasyxiv.com/pl/index.html for any news about any further developments. In addition, it is highly advised that players refrain from replicating this, since it would be considered a very serious violation, and serious action may be taken against players if they are found to be in violation. We greatly appreciate the heads-up!
