Recently, when going through the Low Quality Posts review queue, I failed an audit. Of course, audits have notoriously been inaccurate at times and I have failed other review audits before, but those times I could at least see why I might have made a decision contrary to what others would have made. Maybe an answer was wrong and I didn't catch the mistake, or maybe the answer simply restated what another answer already addressed and I did not realise, for example.
This is the first time I am completely puzzled by the logic of the audit. The question asks for book recommendations on algebraic geometry, and as far as I can tell that's what the answer in the audit provided. I definitely cannot see how the answer is supposedly "spam or offensive". I don't know about the contents of the book, nor do I have sufficient background to understand any of it, but from the Amazon preview it seems to be a perfectly serious, perfectly legitimate textbook. At worst, it might be a horribly written, completely inaccessible text, but that does not make it spam or worthy of deletion, as far as I can tell.
Can anyone explain what the logic might be behind deleting this particular answer?
(To be clear, I am not that upset about failing an audit per se, nor is the purpose of this post about improving the audit system. I really just do not understand the logic behind the deletion of the answer and hope I can get an explanation here.)
