MattMarty - I think the objection above was just to raise the grade for the purposes of sale, even if it wasn't submitted to an official grader. In other words, it's the act of alteration with intent to sell that is frowned on; independent of whether it is submitted for grading or not. In the case of re-submitting a card for higher grade, you're not changing the card at all.
Just because the goal is the same, the moral validity of the action that is used to reach that goal doesn't have to be.
