I'm not here to moralize. In at least some cases, he clearly copied and pasted and then did some minor edits. I don't see how that could have happened accidentally, and therefore I don't think it's unreasonable to ask how having a set of rules is going to help (given that, obviously, it will typically require a certain amount of diligence to follow any set of rules). I'm not saying that it won't help, but if it will, it would certainly be instructive to understand exactly how.
