Dorion I am pretty sure is their full time camera man, you can hear his distinct voice in many of the scenes, he also revealed himself in interviews as you said. He also runs the dogfart facebook, twitter or edits to the website etc. I know Billy Watson owns a lot of porn and is the director behind many websites but I don't think he's behind the camera himself.
It just explains why these guys do this. They are tiny dick guys who seem to have a weird fetish about big black dicks. I have never come such as disgusting pornstar. The Minion stuff he shot was grosse.
