As James May once said to Jeremy Clarkson on Top Gear, I am unspeakably outraged.
As a Listener setter and solver, I don't seek out this site in order to cheat and to spoil my own solving experience. However, the actions of those that do use this site do impact in a massive way on those of us who prefer to solve puzzles under our own steam.
Every time that somebody gets an answer from a clever friend, posts solutions or hints, or points other users of the site towards the solution, it serves to diminish the achievements of those of us who are not either too stupid or too lazy to solve the puzzles on our own, or to persevere when we are stuck.
If you don't know the answer, or can't fathom a puzzle's denouement, then either stick with it until you do, or accept that you can't get a particular puzzle correct and, when the solution is published, read it and learn. That way, you'll actually improve as a solver to the point that you can get the majority (or indeed all) of the puzzles correct, rather than continuingly relying on others to help you over the line.
People who seek help on this site for puzzles, especially the Listener, the most challenging crossword series in the world, are no better than athletes who take drugs to enhance their own performance - and those who willingly supply the answers are no better than those who supply those drugs.
For pity's sake, learn to achieve things under your own steam, and accept that sometimes you don't succeed. Radix, a good friend, will have spent untold hours concocting this puzzle. The cheating that goes on here both diminishes his achievement in constructing the puzzle, as well as the achievement of those of us who spent hours wrestling to bring the puzzle to a successful conclusion.
