So back to the matters at hand.
Umm, do you think the GB movie would have shown the faces of all the men at least once? I believe it would have, unless some super special care was done to avoid it.
This ties into the question how the owners actually recruit their paying members. It's obvious that they don't just hand out carnation club memberships to everybody, but aim for high-class clients instead, and on the other hand they can't just approach a random CEO with "Good evening Sir. May i interest you in our top-level brothel? We aim to please your darkest desires, for a hefty price of course.".
The fatty shown in the video has
definetly the same body model, but there could be a different head on this body.
Vincenzo (the Tenor) is quite a Stallion and can go several times with a very short refractory period in between. I would not rule out that he satisfied his huge libido in some porn shoots back then, under the condition, that his face is not visible in the videos.
If you are familiar with GGG porn shots, they feature huge gangbangs in which most of the male participants are amateurs, who often take great care not to show their faces e.g. by wearing baclavas, and the chosen camera angles also usually try to avoid to capture those male faces. There are some recurring real porn actors mixed into the cast to enable totals, yet the camera direction heavily focuses on the women and the lower parts of the males.
I don't know how complex blurring or pixelation of a face is, but this could be another option, if Vincenzo has participated and wanted to stay anonymous.
It was probably very easy to recruit Vincenzo as a member, if August knew him from those shoots.
Victorias and Vincenzos reaction will be very interesting, should they ever meet. However, for now i don't think we can conclude anything decisively, because it could be very well just another fat dude in that video.
