Some time ago on this NG it was suggested, by John Stevenson, that we should shun Airy. This meant no-one responding to any of his posts, under any circumstances. Given the most recent outburst I feel we should all get together and do this. As several people have correctly pointed out, once you completely ignore a troll he will eventually get bored and annoy people elsewhere. It just requires will power to resist the huge temptation to lambaste him for whatever reason.
