Huh? The link title says: "iBookstore rejects Holly Lisle's writing course because she mentions Amazon"

1) Not "instant rejection". 2) Not "just saying the word Amazon".

She isn't claiming it is an instant rejection I don't think. But it sounds like they flagged it initially based on links, she removed the links and then they said it was actually the content itself.

A Big Six publisher had an eBook rejected by Apple because it mentioned there was also a Kindle edition available.
