I asked about this when I first signed up to lit and was told that it isn't really working yet. I'm not signed up for that reason, but a lot of people who responded said they'd like for it to work.
I am unclear how this would work, but can not imagine a publication or advertising agency checking Writer.Literocity.Com when they need a new feature writer, or copywriter.
Three impossible things before breakfast, I can certainly manage; but that highly developed a sense of fantasy, I do not possess!
If one is seriously looking to develop a career in commercial writing, I would keep Literocity in a separate box from their "serious" writing examples. We have not reached that point - yet - where the two are considered interchangeable. Although, I assure you, that erotica is more difficult to write well, than most advertising copy.
The best one might hope to get from Writer.Literocity.Com is a legitimate offer from a paying porn site, to write stories - to their specifications - for pay.
Even then, one must proceed in a careful, businesslike fashion, with a willingness to become litigious, to ensure delivery of your promised payment.
