^^ And the problem with these... "regular" ... players, is that they will go all over the chats in-game telling people "guess what guys! breaking dirt over chests in region to steal stuff is now legal - Xani and Kainzo said so!!!" --- and then the typical downward spiral of misguided judgment continues on and on.
If all else fails... Exploiting is illegal. It is against the rules. Breaking a dirt block in a regioned area (that you aren't supposed to be able to break), and then opening a chest in the split-second that you have because of lag, is CLEARLY exploiting game mechanics and taking advantage of the lag to benefit yourself. I don't see how this can be disputed. I know the way Xani stated it may be blowing some people's minds, but I can guarantee Xanipher and Kainzo did not intend that message to imply that you could go and break in a bunch of chests in that manner and not face any punishment.
Any other interpretation of what Xanipher said is simply manipulating her words and taking advantage of the fact that she didn't have her post proofread by 4 english majors before posting. When writing something, you don't typically go out of your way to look for logic loopholes or potential ways to misinterpret what you said (well I do, only because I know how people are...but you get the point, hehe).
