Emcee, my post was written late, and more strident than I intended, so many thanks for taking it in such good part. My view is not at all dissimilar from yours. I don't like to see themes and endgames given away. But I took the view it was better to be in the tent looking out, and thereby be in a position to mitigate the damage, than outside looking in with helpless frustration. So I do sometimes post there. That's a personal judgement, of course.
As far as this thread is concerned, Dim16 seems to have been the only new contributor in the last few years. So newer solvers must be gravitating, understandably enough, to sites where they can obtain help. Which leads to my final point, as I've gone on long enough. The average age of a Listener solver must be over 50, probably over 60. For such niche puzzles to survive with such pressure on space in newspapers (and Enigmatic Variations has recently been under severe threat), they need to attract new solvers, or they will wither away. And I think those solvers will be unlikely to go through the learning curve that you and I did too many years ago, and accept that no help at all can be given until the solution is published
