Yeah, Jia never really hid her porn past. In fact, she started out as a personality on BlackVoices in the early 2000s and it was there she declared her intention to get into adult entertainment, and she publicly documented her journey into the world of porn. And after she left and became a pioneer in those early days of pre-Bossip black bloggers (Sandra Rose, Nicole Bitchie etc) she was quiet about her porn history at first, but once people connected the dots, she fully embraced it. At that point, she talked about her porn all the time... she would often draw from her experience in the industry to comment as an expert when the world of mainstream entertainment converged with porn (such as when Pink when her exposure derailed Farrah Franklin's attempt at a Destiny's Child spinoff group, or the scandal around Montana Fishburne, or when Brian Pumper became a popular meme--she talked quite a bit about working with Pumper and how weird and nasty he was, obsessed with sniffing her bootyhole and all that).
The real reason she abandoned her blog and disappeared was because despite her growing success as a blogger, she could not escape her instincts to be a scammer--which she has indulged in for every stage of her career, going back to BlackPlanet. She was selling some sort of product--can't remember now what it was--but she took a boatload of people's money, and jetted.
