Under NO circumstances should you blank out episodes you feel need deleted. Users work hard to enter information into the database and deserve respect. If you feel an episode information needs edited, post in the forums first. This is the MAIN reason series get locked. Also, keep in mind that Admins/Mods have the ability to move, delete, renumber and edit episodes in batches. If 12 episodes of a series are currently in season 2 and should actually be in season 3, there is no need for you as a user to create the 12 episodes in season 3. Simply post in the forum with sources and an Admin/Mod can move and renumber all 12 episodes in less than a minute.
