Deleted Characters Being Reviewed

If I were Nexon, with their renowned delicacy, I'd just go ahead and ban any account that got the skill within the past 2-3 weeks or however long it was, and tell the users to submit a ticket with a preset title if they think they were banned wrongfully. Then set up an automated filter to handle those tickets, and a procedure to check, for example, if the character has any quests completed significantly earlier (indicating it's an old normal adventurer), or still has its KoC link, or the user can provide screenshot proof of having had a KoC at the time the UA was created. Obviously if the char is a Cannoneer or has unreleased hair or eyes, the appeal would be rejected out of hand.

that's just as bad.
