Perma ban is ridiculous. I've seen complaints about people helping friends cubing up these weapons and still being banned. What's to say these players aren't just helping friends or they "found it" cause someone was bragging? Can Nexon provide the burden of proof? Or better yet, all these vindictive children?
They've already set up the precedent year after year that these "dupe" / "exploited" items would end up deleted(unless it is mass exploited like nebs). You know this. We know this. I'm glad a CM is speaking up and saying that's not protocol.
