They were some loose posts on some site, probably 4chan. It was still relatively early in her career and she had like two threesome vids out then, so he could post about it without it leading to some scandal of sorts. Basically, the gist of it is that he went there and fucked her in front of him (from which there's a video) and then the threesome. He did mentioned she is very weird irl, like beyond being quirky and all, and that you can tell she's not quite right in the head, in a way that it made him kinda not wanting to go to a second "date" they had planned. It was mostly that, like two or three posts. If you go to a 4chan archive site and look for sexyflowerwater you might find them. IIRC it was a thread about guys telling stories about appearing as the "male talent" in some egirl's video.
I can give credence to his words because she used to be very open and chit chat with you and she's certainly kinda weird at the very least. I mean, unlike most egirls, not only she welcomes tributes and dickpics, it's like she actually wants to see them.
I think the bit about her inviting subscribers to her threesomes ended up being fake because she dropped that pretty fast.
