What in the title made you think this is about legal matters and not about the experience of a porn-star?
I'd rather read this essay than some opinion of the "legality of online personas". I found it interesting, easy to read and actually thought-provoking.
The title is "Can We Learn About Privacy From Porn Stars?". We, by definition, are not porn stars. We are taken to be the masses of regular folk. The article had almost no thesis points, however, it did have a theme. The theme was the personal experience of a famous person. I assumed that the article had something to do with privacy online. It does not. It has to do with notoriety of famous people.
