I'm an avid puzzler.
Seriously, any help given here usually means that the puzzler has a good grasp on the puzzle and perhaps needs a "nudge".
No-one without a grasp on cryptic, whatever help they may be given can hope to complete any of the themed puzzles, Listener included.
I know The Listener is held dear to some, and it is a competition over the whole year, but that makes it more OK the help out. I'd guess that no-one asking here for help is "elite" enough to have entered every puzzle.
Most asking for help are absolutely delighted to be "half way there".
I don't think helping is doing any harm at all. That's just my opinion, though.
