I absolutely agree with the sentiment there. I've always been surprised how early some solvers ask for help. The Listener isn't meant to be a doddle. The average Listener wil take three hours or more, a difficult one far more than that in my case. To ask for help before at least three hours has been spent on a puzzle is unreasonable in my opinion.
