Aitch - you amongst all M's are most prized etc. but
I remember that post, and I didn't find it extreme - and nor did MNHQ, since it wasnt' deleted. They have a hair-trigger at the mo, so anything that gets through can be reasonably considered to be in the spirit of vigourous debate.
It was personal, in that it was responding to something that vvvqv had said, but I don't think that it was beyond the pale, in context. Many of vvvqv's posts have been very bullish (though she recently suggested that she missed something I'd said on Moldies which explained some posts which involved me - though not other, more general posts).
As far as I recall, Custardo was saying that vvvqv had, since the Moldie revelation, revealed an unseen side which would come as a suprise to most but which she had already clocked. I personally don't find that abusive, in context. It's tough, it's not nice - but is it really abusive? I don't think so.
I have found vvvqv's posts in the last couple of days markedly different from those posted during the first days of this disaster.
