-1. Obviously he had evil intent in the dupe. He obviously knew the dupe worked when he purposely duped his lores. Instead of duping more things to see if it was "visual" (cough, cough, lie), he could've instead dropped the lores and picked them back up to see if it was a true visual glitch. Overall this dupe could've seriously affected the Loka MC community and economy, and I don't know what I would've done if the Loka economy would've crashed. You should've reported the dupe the first time, instead of "testing it" again. Who knows what items you could have duped, rare items possibly, which may now be in circulation, thus ruining the Loka MC experience, and the economy.

(+1 this is a joke, was in vc with him at the time, didn't dupe on purpose, and reported it, plus he burned the items. overall a moderation/admins fault for not responding to it. should be 1-2month ban, hes learned his lesson)
