Citations not needed. There are allegations, nothing more.

If this happened to me, I would find the moral import of the matter significant to the point that it would not occur to me to use it to plug my book.

This may well be an endemic issue at this company, and it does seem that these sorts of situations do in fact exist in some places, but so far there is only one person's story's and without proof.

My interpretation was that the "citation needed" was in reference to "we have seen similar claims before that have turned out to be false or exaggerated greatly".

Ah, I misunderstood. Then, to provide a citation which is related without being analogous: the Duke lacrosse case. See: https://en.wikipedia.org/wiki/Duke_lacrosse_case

Yep
