This video was quite interesting. I've read about Harriet Sugarcookie and seen her website. She does tech and geeky vlogs and interviews, aside from her porn work. It is certainly a unique approach to her brand and business.
I'm of the opinion that as long as there is no exploitation and that the work is a choice, this is a perfectly valid work choice. Seeing how she is able to voice out those concerns and her own perspective on her business is interesting and worth a listen.
