That's not necessarily the point though. While they did initially come up with the idea because pornstars are some of their brand advocates, they realized that it's much cheaper and cost-effective to advertise there as opposed to a NYT or WaPo that has just as many readers, but is also noisier.
That's the point this person is making. They're saying that by advertising on a porn site, they are getting readers from all those websites, because everyone watches porn at some point.
