If you think about it from the perspective of this guy is using the site/setup to scam these girls into fucking him, then how shitty these videos look all of a sudden makes sense. He's definitely not doing this to generate content for the site, which is why no effort is put into quality. The fact that he can sell the videos afterwards, that's just an additional bonus for him and gives his scam an air of legitimacy. Plus I'm sure it's nice when the income from it can offset whatever he compensates these girls when he needs to.
Between the potato quality, the 75 watermarks on each video, complete lack of planning for a shoot, and the huge level of discomfort some of these girls display, I'd be willing to bet money this is more about documenting his own conquests and archival jack off purposes than anything else. The videos being split into so many different parts just supports this.
