I do take your point, and I'm not in any way defending that particular individual. What I'm saying is that in this instance you have information about the background to the question which is influencing the assessment of whether an otherwise legitimate request is appropriate.
If you are providing help, say, to a Listener solver, you will not normally have that background. But what if in December you were tipped off that one of only two all-correct Listener solvers up to that point was struggling with that week's puzzle, was desperate to win the trophy, and was going to be asking for assistance on the forum. Would that influence your decision whether to provide help? If the answer is yes, then it would suggest that the crime is not the cheating but the being found out.
