When is a book actually worth banning?

When a book is published by an anthropologist and is all about students in high school who agreed to be research participants for a master’s thesis, but who were then involuntarily made the subjects in a book. This happened to at least one student at my high school, who was included in the thesis of an anthropology graduate student at an Ivy League school, who then went on to publish her work as a book -- without notifying her, without getting permission from her (although it is possible this student signed away her rights in high school — which, if she did, why was she not notified when the book came out?).

I’d love to name the book but then it might just reopen old wounds for the subjects of the study. I can say it was published by Yale Press and the professor is heavily associated with Stanford University. Stanford University Press, incidentally, published my mother’s master’s thesis during her career as an anthropologist. Not only did all her research subjects know their stories (as survivors of the Cambodian Holocaust) would be published, but one of them even contributed illustrations of Cambodia as it was before the devastation. Social scientists, respect your research subjects. They are human beings.
