ART MONEY/CHOCO : FFXI General Discussions

a while back i read about how u can get the choco effect..as far as speed goes using art money and i have done it before, i was wondering if anyone has ever gotten caught/banned using this method or if it is even possible anymore...another thing, people may not believe me when i say this, but i have actually used art money to buy something from an NPC for 1 gil...now i've done it on 3 occasions, and was never able to do it 2 times in a row...and i only did this in bastok mines in the stables and bought a dart all 3 times..now i never intended to buy something expensive for a cheaper price i was mearly testing if it was possible, and i am going to try and find a way to stick the price, because i was and still am a rookie at using art money and has anyone ever gotten it to stick to do this? as impossible as it is because prices i'm pretty sure are server side, i am telling the truth, and like i said...i only had it happen 3 times...out of 50+ tries, but i bought a dart haha..which sell for 9gil or so hahaha
