Funny that I got mentioned, I was going to post what I can remember from the Mike years, got bear in mind that this was over 20 years ago and most i remember are from promo galleries.
I did a Web archive browse and this is the most complete list from up to 2002, its not perfect as I know Star was on the site by this point (hope the link works)

I think he got rid of most of these girls when he first redesigned the site not long after this was archived. Footage of girls from that list that ive seen and haven't been able to find again online are: the blonde girl Melissa, its bj footage and she gets top less, Danielle which again is bj, Malia which is just her playing with herself, think there was also some return footage of her but if so again just her touching herself. Ive seen intro footage of the girl Mary he picked up but not seen anything else. There was also a girl called Adella thats sleeping at his place that he wakes up and has sex with. I remember some intro footage of him getting ready to confront an employee of stealing from him, based on description I'm guessing thats Stacey but I don't know how it ends. There's also a blonde hair girl called nico, her return footage in a pink top keeps appearing every now and then online but I know there is a first audition sex scene I saw in a promo gallery. Ive also seen different footage of kimberley and melonie (think with her its just looks like bj footage)
This is my memory being fuzzy (again over 20 years ago and mostly from promo galleries) so I'm not 100% on this but I could have sworn he had sex with 22 year old mandy. I thought ive also seen different footage of skye returning after her first audition, same with honey.
From after that to about 2004 missing is Mia a curvy Latin lady who had a bruised lip and was cheating on her bf (full sex scene), also brunette called melonie2 (also full sex scene) and a sex scene with Novalie. The reason why these r not around is that they were only available on the realplayer device he used and when he stopped using that he just didnt upload the footage again. There was a first scene with Jennifer with glasses. There is also a third scene with Anna who returned after a couple of years and gives him a bj and a couple of bj scenes with Claire from sam&claire, think ive also seen footage of yet another stephanie scene that never got uploaded.
From 2005 onwards I remember seeing a return sex scene with the large girl with glasses (Maria?) It's not him having sex with her though, don't know who. I remember seeing preview footage of Diana and chloe returning (separately) but neither scene was uploaded. In a remaster of Anna's first time there is a short preview of a girl, i think her name was Danielle and there was a 2 minute preview of her on the site but it just bringing her into the hotel room and chatting, again full scene was never posted. At the time He had several pictures of girls on the site enterance that he never uploaded and some of the ones he did, took months before he posted them.
The big scene he mentioned more then once but never posted was a anal sex scene with Sam from sam/Claire, I know I'm not the only one that remembers him talking about this, he also has hinted back when he was bit more social that he had additional footage of Marie and Kim from the early years he never posted.
He mentioned a scene that sounded like it only stayed up for a day, I think it was about a sister to Shannon from 02/03, if true have no idea if Shannon was also in scene and if it is true.
Lastly I remember some guy commented on some scene that been uploaded but unedited and therefore taken down not long after, I think it was a 3some with merrissa and another girl but I don't know if its true.
And thats all I can remember, as far as I'm aware all videos that he uploaded from 2006 to when he quit are avaliable on here.
