The article is about strippers, not cam girls (not that there's much difference, one is in a club while the other is at home), but #3 applies to all sex workers, with testimonies from 7 people who work in clubs, and conclusions drawn from one scientist who worked as a stripper to gather data.
Also, "false sense of attention and self confidence"? It's not false when a bunch of people are devoting time to watching you do something and are paying money for it.
