On the off-chance that you are genuine Matt, and for the benefit of other forumites, the young lady to whom you refer is probably:
I had lengthy conversations with the head of one of the UK's largets adult distributors some time ago over the identity of the young woman. Although a dead ringer for the person in the video, 'Robyn' maintained it wasn't her. You will also see from her listing that she has insisted that her picture is removed and her real name is not even listed as an alias.
Chances of her agreeing to appear on Channel 4 are therefore remote.
