Just an outsider's view.
I have both 3Y1VC and 3Y5X QSLs accepted for DXCC many years ago so just planned to work 3Y0J on some bands for the Challenge purposes. Worked then on 30 meters and after numerous requests by pilots NOT to work 3Y0J on other bands or modes i quit not knowing that it was just a pilot's joke.

Lesson learned.
Anyway, after reading the seven page opus by VK6CQ the obvious question arouse:
Who will benefit if 3Y0J operation will not get DXCC credit?
The answer is quite obvious – some influential group or resentful individual who decided, for some reason, to discredit the 3Y0J operation.
As long as the operation was a land based “foot on the ground” one, the only possibility for them to question its legitimacy was so called “landing permit” as the only DXCC rules paragraph which can affect the operation. The rest, like “disregarding of safety protocols, etc” was just pure demagogy.
Kenneth Opscar gave the comprehensive answer on “absence of landing permit” accusations and hopefully this is the end of the story.
Lessons I learned from this and other DXPeditions in general and VK6CQ’s attempts in particular:
1. In accordance with “Miranda warning”, before DXCC approval, NEVER publish any documents, pictures, videos, interviews etc prior or during the operation, as those can be used by some jealous groups or individuals to discredit the operation.
2. Ignore the DXPedition pilot’s warnings and requests. Recent “Not to Work Them” example has shown that the pilots can be useless and even harmful.
And finally: it was Norwegian Roald Ammudsen who, as the first man on Earth, has reached South Pole. “Teaching” Norwegians how to make Polar expeditions successful is counterproductive and even foolish.
