Nope. Why? The reasons you just gave.
First, they were drunk? They should be forced to keep it just so every time they see it they will think "man that was stupid. maybe I shouldn't get sloppy drunk."
Second, they typed it wrong? LOL! The legacy system is a fairly important feature to you characters, if they couldn't type it right the first time what on earth makes you think they would have the ability to type it right the second time?
Last, didn't know what they were doing? Then that's just plain incompetence or laziness. No hand holding for idiots.
I think a better idea would be for people to pay attention to what they are doing.
