Just goes to prove that a really good removal job can beat the grading system of even the best graders. I think we've had threads on this exact issue before. Asking a grader to pick up a professional-caliber wrinkle or writing removal in many cases is asking the most difficult task for the grader. Not a justification, merely an explanation.
I've noticed that none of the graders are consistent w/r/t handling of writing on cards, removed or otherwise. Sometimes they grade them, sometimes they refuse to grade them as altered.
I do not fault any grading service for not keeping a photographic archive of graded cards. It would be impossibly expensive to go through an archive looking for every card submitted to see if it was the same. No one could afford to pay for that kind of time.
