Okay as much as I love the Maplehood event... And I know many people do these quests on various characters...
Can I (and possibly the entire maple community) request that you DO NOT DO MAINTENANCE ON A THURSDAY? During the event? It really makes trying to do the quests tough when people have work commitments, school commitments, and 4-8 hour+ maintenance too.
Or... Move the typically Thursday events to another day entirely...
Good that Nexon have finally been proactive in removing duped items (Now can we deal with these pesky meso sellers in-game?! They're everywhere!)
As for the punishment, good that all people got perm banned. "Knowingly or unknowingly". You see an item that seems 'way too good to be true' then guess what?! DUPED/HACKED/ILLEGITIMATE ! Whatever you want to call it.
You may see it as 'unfair', but you know what? LIFE IS UNFAIR! You just get back up after being punched down, and play by the rules. It's so simple!
