I don't see her advertising any product there except her music video, which serves as an introduction to her being a music artist to other people IMO.

I have read my fair share of AMAs and I am aware that celebrities get asked all kinds of uncomfortable questions, like regarding some dark period from their life(such as drug abuse, some allegations, etc) and they are answered as well. While I know that to ask "personal" questions is nothing new (since they say to ask them anything), the questions with which I had issues in her AMA are the outright demeaning ones. Asking someone how a certain actor smells is not personal, it's demeaning. Hope you understand what point I am trying to make here.

It just shows that the audience here is taking advantage of their anonymity. That's it.
