Amazon's Sensitivity Filters

Some of my Amazon Reviews are hidden by sensitivity features. That means you won’t see them on my profile, but they will be on the product page.

I don’t really care, but I’m curious how products are classified as sensitive. I don’t think a book about baking bread is sensitive.

Amazon says:

Public activity or contributions associated with products classified as sensitive will be hidden from your public profile automatically. These products include certain personal care products, jewelry, intimate clothing, self-help, erotic media, and products used for personal protection.
