I can't see why anyone would really object to the sharing of answers to daily, non-prize puzzles. But then again, if it's 'only a crossword', why the impatience to know an answer NOW, when nothing depends on it? Put it down, watch some TV, go shopping, play football, sleep on it, and the answer might come to you when you pick it up again. If not, then admit defeat, fill it in Gielgud-style, throw it away and get on with the rest of your life. Nobody will die because of a few blank squares. The only possible injury is bruised pride.
Begging for answers defeats the self-challenge, which is surely the whole point of attempting a crossword in the first place.
