sendtorc("/reset account");

Make a database with an array of all the accounts that have been reset. When someone logs on it will check if that players account is in the array, if not it will reset them and add them to the list. Then when you want another reset, you just reset the database.

Of course I prefer to save to a file so that when the NPC Server has to be reconnected or anything like that the list isn't lost. (Therefore resetting everyone)
