Whois 008

It's been a long time. I've realised that sometimes the answers are too obvious because the people are too obvious. I mean, there are people who would be your first guess not because of the clues but because they're the sort of people you would guess at random. So I resorted to obfuscation, occultation and obliquity in my quest for the ideal frame-up; but time and chance happened to them all. I am going to try a new tack. If you can solve any one of these riddles, it will point you straight at the subject of this Whois challenge. Or at least, give you a very good clue.

On seven hills this city stands,
Archdiocese over two lands;
Holy and eternal city,
But not Rome and more's the pity.

The eyebrows are a giveaway,
The shadowed eyes that see not day;
One walks the night by internet
And sells one's stuff for free I bet.

The wild Tibetan yak appears,
To the Skinner it now endears;
This is the offspring of that pair,
The one of convoluted air.

Look out for the Chinese scholars,
Those with sense but fewer dollars;
Cohabitation saves the day
At the impromptu loading bay.

Yes, I'm aware that this is all very peculiar, and that it's somewhat less than 500 characters in length. I'm in that kind of mood though. Heh. Oh yes, before you make a guess, make sure that all four stanzas are fulfilled! Oddly enough, the clues in the first and third verses have already been referred to somewhere else in this blog.
